ExtraGroups addon v1.0.1 is now released!
ExtraGroups addon is an addon simplying your animation workflow.
You can manage your bone groups (create / delete / sort groups, and adding / removing bone(s) from groups).
For each group, you can use some operators (you can customize which one are displayed, and in which order).
This is a bug correction minor release. It corrects a bug with Lock and Mute, when there is an animation on bones, but without any keyframes.
Here are some screenshots and video of the addon:
