+:doc:`Bone Collections </animation/armatures/bones/bone_collections>` are used to group related bones together
+so that they can be hidden or revealed together.
+
+Rigify can take advantage of collections to generate extra features and the user interface for the final rig.
+A panel named :ref:`Rig Layers <rigify.rig_ui_template.RigLayers>` is generated with buttons for hiding the
+collections, arranged in an intuitive layout.
+
+The Bone Collections UI panel allows configuring the layout of that generated panel, as well as specifying some

+
+The top of the panel is occupied by a list that duplicates the main bone collection list, but displays additional
+properties, such as the color set, whether the collection has a button, or whether it generates a selection set.
+
+Validate Collection References
+  Some sub-rig types have :ref:`references <bpy.types.RigifyParameters>` to bone collections in their properties.
+  Rigify uses a referencing scheme that is robust to collection renames, but deleting collections or joining armatures
+  can still lead to broken references.
+
+  This button runs a scan that validates and normalizes all collection references, reporting any errors, and
+  reducing the chance of breakage being caused by subsequent user actions.
+
+  This scan is also performed automatically every time the rig is generated.
+
+  .. warning::
+    To avoid breakage this operation should be used both immediately before and after joining two metarig armatures.
+    More specifically, it must be always done between the actions of renaming any collections and joining.
+
+Color Set
+  Specifies the :ref:`color set <bpy.types.Armature.rigify_colors>` to use for bones in this collection. If a bone
+  belongs to multiple collections, in general the collection located earlier in the list has priority.
+
+Add Selection Set
+  Specifies whether a selection set should be generated for this collection.
+
+UI Row
+  If nonzero, specifies which row of the :ref:`Rig Layers <rigify.rig_ui_template.RigLayers>` panel should contain the
+  button controlling the visibility of this collection. When zero, no button is generated, and the collection is hidden.
+
+UI Title
+  This field can be used to override the title used on the UI button to be distinct from the true collection name.
+  Unlike collection names, titles are not required to be unique, so this can be used to reduce clutter by relying
+  on contextual cues within the panel.
+

+-------------------
+
+.. figure:: /images/addons_rigging_rigify_metarigs_bone-collections-layout-panel.png
+   :align: right
+   :width: 300px
+
+The UI Layout sub-panel provides a WYSIWYG editor for the layout of the generated UI panel
+(as defined by the UI Row and UI Title settings above).
+
+Each row contains three buttons at the end:
+
+Arrow
+   Moves the active collection button to this row.
+Plus
+   Inserts a new row before the current one.
+Minus
+   Removes the current row and shifts all buttons up.
+
+To the left of the editing control buttons, rows display buttons corresponding to the collections, same as the final
+UI, except that rather than hiding or unhiding, clicking these buttons selects the collection.
+
+For the active collection the selection button is replaced with an input field for editing the UI Title, and an **X**
+button to unassign the collection from the UI.
+
+For any collections not assigned to the UI, their select buttons are displayed in a separate section at the bottom
+of the sub-panel.
+
+The ``Root`` collection will be added and/or assigned a UI button automatically if necessary when the rig is generated.
+If desired, it is possible to manually assign UI buttons to the internal ``ORG``, ``DEF`` and ``MCH`` collections.
+

+of that name, it is positioned at the origin of the rig object. Its widget looks like
+a circle with four arrow shaped protrusions.
+

+
+Limb Master
+^^^^^^^^^^^
+
+Many limb-like sub-rigs have a gear-shaped bone at their base.
+
+This bone can in some cases be used to transform the whole sub-rig as a rigid unit, and is also used as a container
+for its custom properties that are displayed in the *Rig Main Properties* panel. If you are looking in the Graph editor
+for the animated values of the properties, this is most likely the bone to look at.
+
+As an exception, if multiple controls of the sub-rig need their own copy of conceptually the same property,
+it may be placed on those controls directly instead.
+
+Tweak Controls
+^^^^^^^^^^^^^^
+
+These controls look like blue spheres in the default color scheme, and are the final control layer above the
+deformation bones themselves.
+
+Tweaks are subordinate to the general IK or FK limb position but can be moved apart, twisted and scaled freely,
+even reaching virtually impossible limb shapes.
+
+Rubber Tweak
+   .. figure:: /images/addons_rigging_rigify_rig-features_rubber-tweak.png
+      :align: right
+      :width: 200px
+
+   Some sub-rigs provide a slider in their *Rig Main Properties* when tweaks are selected, which controls
+   the smoothness of the Bendy Bone joint at that position. When zero, the joint deforms with a sharp bend,
+   while setting it to 1 makes the transition smooth for a more rubber hose cartoon like appearance.
+
+Custom Pivots
+^^^^^^^^^^^^^
+
+Some bones that can be freely moved in space (like IK controls) can be optionally accompanied by a custom pivot
+control. These controls usually look like a plain axes empty with the axis lines capped with squares or crosses,
+like the one in the image above. The control can be freely moved to change the location of the pivot, and then
+rotated or scaled to transform the target bone around the pivot.
+
+IK and FK Switching
+^^^^^^^^^^^^^^^^^^^
+
+.. figure:: /images/addons_rigging_rigify_rig-features_ik-fk-switch.png
+   :align: right
+   :width: 200px
+
+A number of rig types provides both IK and FK controls (red for IK and green for FK in the image above),
+with an ability to switch and snap between them.
+
+Switching is controlled by a slider in *Rig Main Properties*, usually blending between full IK at 0 and full FK at 1.
+
+Snapping one type of controls to the shape of the other is done via buttons, which form a group of three
+in their complete set:
+
+* The main button will snap on the current frame, and auto-key the result if enabled.
+* The *Action* button will bake the change on multiple keyframes, according to *Rig Bake Settings*.
+* The *Clear* button will delete keyframes on the corresponding controls within the bake interval.
+
+Parent Switching
+^^^^^^^^^^^^^^^^
+
+.. figure:: /images/addons_rigging_rigify_rig-features_parent-switch.png
+   :align: right
+   :width: 200px
+
+Some freely movable controls, e.g. usually the IK controls, can have a mechanism to switch their parent bone
+between a set of choices, including the root bone, or none at all.
+
+This mechanism is exposed in the *Rig Main Properties* panel through a row with three controls:
+
+* A button that presents a dropdown menu, which allows switching the parent on the current frame while
+  preserving the bone position and orientation in the world space.
+* An input field that exposes the raw switch property for keyframing and direct manipulation. Values correspond to
+  positions in the dropdown list.
+* A button to apply the position preserving parent switch over the bake range of keyframes.
+
+.. note::
+   When manually placing a Child Of constraint on the control bone, the built-in parent should be switched to none.

+Fingers & Tentacles
+===================
+
+Simple Tentacle
+---------------
+
+.. figure:: /images/addons_rigging_rigify_rig-features_simple-controls.png
+
+The simplest type of rig for a finger or appendage in general is the
+:ref:`simple tentacle <rigify.rigs.limbs.simple_tentacle>` sub-rig. It has only basic FK controls and tweaks,
+with the only automation being the ability to copy the local rotation of a FK joint to the next one.
+
+Advanced Finger
+---------------
+
+.. figure:: /images/addons_rigging_rigify_rig-features_finger-controls.png
+
+For the case of fingers, there is a dedicated :ref:`finger <rigify.rigs.limbs.super_finger>` sub-rig type,
+which provides:
+
+Master
+   A master control, which can be used to rotate the finger as a whole, as well as to bend it via Y scaling.
+FK Chain
+   FK control chain (green) that can operate as semi-tweaks through allowing translation.
+IK Control :guilabel:`Optional`
+   IK control for the tip.
+
+   .. note::
+      IK in this sub-rig is rudimentary and operates as an adjustment for FK. The intended way of use is to pose
+      the finger in FK, and then use FK->IK snap and enable IK if it is necessary to pin the tip of the finger
+      in place.
+
+The properties panel has the following features:
+
+.. figure:: /images/addons_rigging_rigify_rig-features_finger-properties.png

+Spline Tentacle
+---------------
+
+.. figure:: /images/addons_rigging_rigify_rig-features_spline-controls.png
+
+   Spline Tentacle (Stretch To Fit, Manual Squash & Stretch)
+
+.. figure:: /images/addons_rigging_rigify_rig-features_spline-controls-tip.png
+
+   Spline Tentacle (Direct Tip Control)
+
+The :ref:`spline tentacle <rigify.rigs.limbs.spline_tentacle>` is an advanced rig for a flexible appendage (tentacle)
+based on the :doc:`Spline IK </animation/constraints/tracking/spline_ik>` constraint. The IK control bones manage
+control points of a Bezier spline curve, which in turn is followed by the IK chain.
+
+The tentacle can be generated in three major modes:
+
+Stretch To Fit
+   In this simplest mode all bones of the sub-rig deform chain follow the curve and squash & stretch to match
+   its length.
+Manual Squash & Stretch
+   This mode is almost the same, but the chain does not automatically scale to match the curve length.
+   Instead, it tries to cover as much as possible of the curve given its manually scaled length.
+   If the curve is too short, the chain will overhang it and straighten out, but this is not fully stable.
+Direct Tip Control
+   This mode is more similar to the behavior of IK limbs: the final bone of the chain is directly controlled by
+   the tip IK control, while the other bones of the chain stretch and follow the curve to bridge the gap.
+
+The tentacle sub-rig has the following control bones:
+
+Master
+   The tentacle has the same gear master control as other limbs (seen as a line in the images).
+IK Start
+   The IK control at the base of the tentacle, which can be used to control the base twist and sideways scale, and
+   is one of the potential switchable parents for other IK controls.
+
+   In the *Manual Squash & Stretch* mode it controls uniform scale of the tentacle.
+IK Start (Extra) :guilabel:`Optional`
+   Extra start controls, optional and hidden by default. Switchable parents default to the *IK Start* control.
+   The scale of the control may optionally affect the thickness of the chain via the radius of the curve point.
+IK Middle
+   Controls for the middle of the curve. The switchable parents default to *Master*, but may be set to
+   *IK Start* or *IK End* controls.
+   The scale of the control may optionally affect the thickness of the chain via the radius of the curve point.
+IK End (Extra) :guilabel:`Optional`
+   Extra end controls, optional and hidden by default. Switchable parents default to the *IK End* control.
+   The scale of the control may optionally affect the thickness of the chain via the radius of the curve point.
+
+   The *Direct Tip Control* mode adds one more extra end control next to the middle ones that cannot be hidden.
+IK End
+   Controls the last control point of the curve, and is one of the potential parents for the other chain controls.
+
+   In the *Direct Tip Control* mode also directly controls the last bone of the chain.
+IK End Twist :guilabel:`Optional`
+   * *Stretch To Fit*: controls the twist of the tip of the tentacle, interpolated to nothing at the base.
+   * *Manual Squash & Stretch*: also controls the scaling of the tip of the tentacle.
+   * *Direct Tip Control*: does not exist.
+FK Chain :guilabel:`Optional`
+   If enabled, the rig has an alternative fully FK control chain.
+
+The properties panel has the following features:
+
+.. figure:: /images/addons_rigging_rigify_rig-features_spline-properties.png
+   :align: right
+   :width: 200px
+
+Start/End Controls :guilabel:`Optional`
+   If extra controls exist, this property controls how many of them are visible and active.
+
+   When a control is disabled, it is snapped to a position extremely close to the corresponding end control point,
+   thus effectively neutralizing its effect. Thus, changing the setting during an animation can cause jumps.
+
+   The plus and minus buttons can help with maintaining a continuous transition in an animation by keyframing the
+   change in the property value with Constant interpolation, and also snapping and keyframing the control itself
+   to its 'hidden' position.
+
+End Twist Estimate :guilabel:`Optional`
+   In the *Direct Tip Control* mode the twist at the end of the tentacle is deduced from the orientation of the
+   tip control. However, for technical reasons, that is only possible within the 180 degrees range of neutral.
+
+   A long tentacle can accept more twist than 180 degrees, so a workaround is necessary. This property allows
+   specifying an approximate estimate of the twist value, and the rig then applies the automatic correction within
+   180 degrees of this value.
+
+IK-FK, IK<->FK Snapping :guilabel:`Optional`
+   If the FK controls are enabled, these provide standard IK-FK switching and snapping.
+
+   However, unlike other limbs, for this rig automatic IK to FK snapping can only be approximate and requires
+   manual tuning. For this reason, buttons for baking the snapping over a range of keyframes are not provided.
+
+Parent Switch
+   Switches the parent of the active IK control.

+This rig type implements a flexible tentacle with an IK system using the Spline IK constraint. The control bones
+define control points of a Bezier curve, and the bone chain follows the curve.
+
+The curve control points are sorted into three groups: start, middle and end. The middle controls are always
+visible and active, while the other two types can be shown and hidden dynamically using properties; when enabled
+they appear next to the corresponding permanent start/end control and can be moved from there.
+
+Extra Start Controls
+   Specifies the number of optional start controls to generate.
+Middle Controls
+   Specifies the number of middle controls to generate.
+Extra End Controls
+   Specifies the number of optional end controls to generate.
+Tip Control:
+   Specifies how the curve stretching and the final control bone work:
+
+   Stretch To Fit
+      Stretches the whole bone chain to fit the length of the curve defined by the controls.
+
+      An end twist control is generated to control the twist along the chain.
+   Direct Tip Control
+      Generates an IK end control, which directly controls the final bone of the chain similar to how
+      regular IK works for limbs, as well as controlling the end of the bezier curve. The middle bones of
+      the chain stretch to follow the curve and cover the gap.
+
+      The rig automatically deduces twist of up to 180 degrees based on the orientation of the end control.
+      Higher amounts of twist have to be dialled in through an End Twist Estimate slider to avoid flipping.
+   Manual Squash & Stretch
+      This mode allows full manual control over the chain scaling, while the chain covers as much of the curve
+      as it can given its current length.
+
+      The start control of the chain manages its uniform squash & stretch scale, while the end twist control
+      manages both the twist of the chain, as well as its scale at the tip (blended gradually along the length).
+Radius Scaling
+   Allows scaling the controls to control the thickness of the chain through the curve.
+Maximum Radius
+   Specifies the maximum scale allowed by the Radius Scaling feature.
+FK Controls
+   Generates an FK control chain and IK-FK snapping.
+Assign FK Layers
+   If enabled, allows placing the FK chain in different bone collections from the IK bones.

+Bone Collections
+****************
+
+:term:`Bone Collections <Bone Collection>` group the bones of an
+:term:`Armature` into named collections. The armature is the owner of these
+collections, so they are available in all modes. Bone Collections are identified
+by their name, which are unique within the Armature.
+
+In the text below, "collection" is understood to refer to "bone collection";
+:term:`Scene Collections <Collection>` are not described here.
+
+Bone Collections can be managed via :ref:`the Armature and Bone property panels <bpy.types.BoneCollection>`.
+
+
+Visibility
+==========
+
+Bone Collections can be shown & hidden via the list in the Armature properties,
+as well as via the list in the Bone properties. Bone visibility is determined by
+the visibility of its collections, and its own 'hidden' property:
+
+- If the bone itself is marked as 'hidden', it is invisible regardless of the
+  bone collections.
+- A bone is visible when it is contained in any visible collection.
+- A bone that is not assigned to any bone collection is visible; otherwise it
+  would be impossible to select it & assign it to a collection.
+
+.. _bone_collections_library_overrides:
+
+Library Overrides
+=================
+
+Bone collections can be added using library overrides. For this to work, both
+the armature Object and the Armature itself need to be overridden.
+
+Limitations
+-----------
+
+There are a few limitations when it comes to bone collections & overrides:
+
+- Only bone collections that are local to the current blend file can be edited.
+- Bone collections that already existed on the linked-in Armature are read-only,
+  and only their visibility can be toggled. Those visibility changes won't be
+  saved, though.
+- Custom properties of overridden bone collections cannot be edited in the
+  properties panel. Python access is fine; this is just a current limitation of
+  Blender's UI code.
+
+How It Works
+------------
+
+Bone collections added via overrides are 'anchored' to the preceeding
+collection, by name. Here is an example. The *italic* collections are defined on
+the linked Armature in `armature.blend`. The **bold** ones are added by
+overrides in `armature_shot_47.blend`.
+
+- *FK Controls*
+- *IK Controls*
+- **Left Pinky** (anchored to "IK Controls")
+- **Right Pinky** (anchored to "Left Pinky")
+
+Now if the Armature in `armature.blend` gets updated with two more collections
+it might look like this:
+
+- *FK Controls*
+- *IK Controls*
+- *Face Controls*
+- *Face Detail Controls*
+
+After reloading `armature_shot_47.blend`, it will look like this:
+
+- *FK Controls*
+- *IK Controls*
+- **Left Pinky** (still anchored to "IK Controls")
+- **Right Pinky** (still anchored to "Left Pinky")
+- *Face Controls*
+- *Face Detail Controls*

+Some history
+============
+
+Bone Collections were introduced in Blender 4.0, as a replacement for armature
+layers and bone groups. Bone Collections are owned by the Armature, so they are
+available in all modes. To contrast, bone groups were stored on the object's
+pose, and thus were not available in armature edit mode.
