Hi all,
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).

Version 1.0.1 is now available on gumroad and BlenderMarket.
Complete documentation is here.

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:
