I never missed some general purpose annotation, i.e. a block of text, to be placed somewhere in the drawing area.
However, what I would find useful is to add some explanations on individual constraints. Currently I can give them a speaking name, which is already great. But from time to time I'd like to add a bit more info about the
why, for my future self. I made a quick mock:

The presents of such notes could be displayed with a little "(i)" beside the constraint in the drawing area and/or task panel, unveiling the text on mouse-over like a tool tip.
When dealing with "hundreds of sketches" I assume the "Label2"-Property, aka "Description" in the tree, would be more useful than annotations only visible when editing a sketch... but I've never been such a power user.
