Extragroups is a Blender add-on from developer BleRiFa aimed at animation workflow. It manages bone groups and brings all your operators under the mouse cursor, keeping the add-on's functions centred on rigging and animation tasks.
The add-on is listed for Blender version 3.2 and released under the GPL license. Complete documentation is hosted on the developer's site, covering how the tool works, and a demo video is available. BleRiFa is also listed as a Blender Development Fund contributor.
Extragroups sits in the superhive library among rigging and animation tools. It carries a five-star rating from a single review, so feedback is limited, though the add-on has recorded over forty sales. For animators who spend time organising bone groups and want operators under the mouse cursor, it offers a focused set of functions rather than a broad toolkit.
