About Node Annotator

Node Annotator is a utility add‑on for Blender that streamlines documenting and maintaining node graphs. After installation it adds a “Node annotator” panel inside the Node tab of any graph editor. The panel offers one‑click creation of a yellow annotation box that automatically generates a text block and opens the text editor, as well as an edit function to modify existing annotations. A Description field links to the Blender 4.2 node‑group tooltip property and displays an info icon on node groups that have a description, which can be disabled in preferences. The refactoring tools let users search for specific custom node groups in the current tree, view each match, replace individually or replace all occurrences with a chosen alternative. The add‑on is released under the GNU GPL v3.0 or later.
