This add-on provides tools to manage large numbers of animation curves in Blender's Graph Editor. It helps organize the list of curve groups in the left panel, making the workspace easier to navigate when specific FCurves are hidden. Additionally, the tool includes synchronization features that link the visibility of FCurves in the Graph Editor to their corresponding armature pose bones in the 3D viewport. Users can configure this to synchronize pose bone visibility with either all visible FCurves or only the selected ones.
