Annotations and notes in node graph.

Hi - I've searched far and wide and cannot find any information on notes or annotations within the color (node) graph (not the editing timeline). I guess I'm looking for something lke the stickynote in Nuke so you can keep easy track of your grading decisions etc - the labelling thing is useless as it truncates your title in the node graph for some reason (Why God why?!)

Basically I want notes in the color node graph window that I can see. Is this possible?

Any help appreciated. Thank you

James
