Blender Armature Graph Tools

When you work with a really big amount of Animation Curves in Blender's Graph Editor you may want to hide some of them (which you don't need to inspect currently) in sake of making the Graph Editor workspace more clear and readable. However the presence of the FCurve at the main Sheet doesn't affect the list of the Groups in the left panel of the Graph Editor. Which means you'll need to scroll this list all the way down searching for the Groups containing those very FCurves you wanted to left visible.

Generally this add-on was inspired by this claim. It doesn't add the functionality meant in this claim (as we cannot simply subtract the Groups from the Graph Editor with Python API) but at least helps you to keep the list of the Groups in a more organized way.

The second sector of the add-on is dedicated to synchronize the visibility of the Grpah Editor's FCurves with the relevant Armature's Pose Bones in the Viewport. You can also force it to syncronize the Pose Bones visibility not with the Visible FCurves but with the Selected ones (in other words, with those which keys are selected in the Graph Editor).
