Quick ToolBox is an interface extension that provides an alternative to Blender's default tool menu, accessible via a hotkey in any operational mode. It dynamically updates to display the relevant tools and brushes for the current context, including Object, Edit, Sculpt, Grease Pencil, Node Editor, and Video Sequence Editor modes.

The interface allows users to view tools alphabetically, customize the grid layout, and access tool properties directly from a built-in sidebar. It includes a pagination system, thumbnail views for brushes, and specific top-bar toggles for Grease Pencil features like auto-merge and multi-frame. The toolbox can be set to appear at the current cursor position for faster tool access during detailed workflows.
