Blender Grease Pencil Shift and Trace

A shift and trace add-on for Blender grease pencil. Allows you to move/rotate/scale the next and previous onion skins. I do not intend to make any major changes to this. It is verified to work with Blender 4.0.

There is a known issue where scaling before moving the pivot point causes the onion skin to jump. Fixing this would require a lot of math knowledge I don't have.

To install, go to Edit->Preferences->Add-ons, click "Install" and select the .py file you downloaded. The Shift and Trace panel will appear in the viewport under "Misc" when a grease pencil object is selected
