ExtraGroups add-on is a perfect companion for every animator.
It’s very similar to the Bone Selection Sets add-on that comes in blender, but 100 times more powerful, fully featured, among some of these, the ability to select, add or subtract selection of groups, has a quick access with the Q key, you can import and export selection groups for when you’re using similar rigs ( i.e: multiple characters rigged with blenrig, or rigify ), you can solo controls, key a group, and even come up with your own setups!
Enjoy!
