System Information
Operating system: Windows-10-10.0.19043-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1650/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 551.23

Blender Version
Broken: version: 4.1.0, branch: blender-v4.1-release, commit date: 2024-03-25 20:42, hash: 40a5e739e270
Worked: possibly never?

Short description of error
Rip Region and Rip Edge tools in mesh edit mode have automatic mirroring that make it impossible to create patterns with them. When ripping parallel edges in one direction, it the middle (or sometimes at random point) it mirrors, and rest of the edges are going in the opposite direction.

In this example I want them all to go in one direction, to create a pattern, but in the middle it mirrors. No mirror modifier or symmetry enabled (This tool actually doesn't support symmetry)

Exact steps for others to reproduce the error

Add plane and create loop cuts in one direction
Without deselecting new edges, choose rip region tool and push them upwards

This is expected behavior as the "Rip Region" tool in Blender depends on the mouse position.
When you use the tool to rip a region, one edge is "ripped" into two, and only one of them is moved. The edge that is moved is the one whose face is closest to the mouse cursor.

This is a useful workflow in most cases.

So not a bug AFACS.

Thanks @mano-wii for explanation. I have follow up questions if you don't mind.

If you do rip with V shortcut it works as you described, but when using tool, you can't drag from anywhere besides the gizmo, and it's always centered. So, how would one use tool and also position mouse correctly?

Reason I'm trying to use tool and not shortcut is that tool has "Fill" option that doesn't appear in redo panel. Is that a bug? If it is I'll report that as new issue.

In general for this tool I hope to have gizmo that can either be repositioned by dragging it, or clicking on empty space should start modal operator. It would also make sense if gizmo responded to pivot point, so you could set it at active or 3D cursor and not have it always in bounding box center. Current state is pretty much unusable.

Some options are hidden in the redo panel. But you can enable then in the keymap settings.
"MESH_OT_rip_move" is a macro, it calls the operators "MESH_OT_rip" and "TRANSFORM_OT_translate".
"MESH_OT_rip" does not have exec callback, so for that operator, Redo is unsupported.
If you find this limitation inconvenient, you can report it as a feature request for the developers to consider adding it to the redo panel as well.

Regarding the gizmo's usability, I understand your feedback. Having the ability to reposition the gizmo by dragging it or starting the modal operator by clicking on empty space would indeed improve the usability. Additionally, having the gizmo respond to the pivot point, allowing it to be set at the active element or 3D cursor, would also be beneficial. I encourage you to share your thoughts and suggestions in the appropriate channels for user feedback and feature requests.
