Most properties in Blender's interface follow the style:
Name | Value
Where the names are front-aligned and the value is back-aligned with the next properties below.
This is due to the fact that `Layout.use_property_split` is by default `True`.
Avoid breaking this convention.
Since a generic snap cursor was implemented (which can be used by Tools and by DragDrop), the Placement Settings are no longer properties of the "VIEW3D_OT_interactive_add" operator.
They now are part of the `ToolSettings` and can be used for:
- Drag and Drop
- Measure Tool
- Placement Tool
This makes the interface confusing, as the user doesn't know where to edit the Placement Settings for Drag and Drop.
The solution proposed in this PR is to move the Placement Settings to the Options popover (top right hand corner).
