This add-on adds a dedicated tool tab to the Graph Editor sidebar for managing channels and editing keyframes in bulk. It provides operations to isolate selected channels and allows users to change interpolation and handle types for multiple keyframes simultaneously. The toolkit includes operators to apply absolute frame and value numbers to selected keys, or offset them by specific amounts. Additional utilities provide the ability to copy and paste keyframe values, insert keys on selected channels, and toggle the visibility of Bezier handles. The add-on also features a batch modifier tool that can add or remove F-Curve modifiers, such as Noise or Cycles, across multiple objects or pose bones directly from the viewport selection.
