Wiggle Bones

Im glad this was useful to you!
The automatic sync the original Wiggle 2 had worked like a charm up to Blender 3.6, but it was quite unsafe in 5.0. When I adapted the original sync to work in Blender 5.0, it resulted in an infinite recursion that crashed Blender.

Since Blender already provides a builtin way to change all selected bones at the same time, just holding ALT, I decided to simply remove the problematic auto sync. This way it is also consistent with how you would sync edits on other objects. Alternatively, you could use the "Copy to selected" button.
I haven't ruled out adding the sync functionality back, if I ever think of a safe way to implement it ;)

Edit: Bone sync implemented!
