There is many manners to save notes to the scene. Usually I put notes to dummy helpers with descriptive names and location to remind me something for concrete object, layer or the whole scene, so I use multiple targets to hold my notes, and any 'popup' persistent callbacks not sound good to me. Also I intend to control which of them to see on loading, so, this helper plugin is written mainly for my workflow, but hope it`s welcome to someone else.
