Whippet GP is an add-on designed to accelerate storyboarding workflows using Grease Pencil. It introduces custom operators for managing timeline keyframes, allowing users to add, duplicate, insert multiple frames, and clear layers directly from Draw mode. The tool consolidates essential Grease Pencil menus into a single side panel. This includes a layer management interface for quick object setup, a modified brush selection menu that displays more options without scrolling, and a list of available Grease Pencil materials.
