Feature request - ability to add 'notes' to a document. I'd imagine these as toggleable divs that would be able to be inserted anywhere in the doc, then made visible or not by toggling a class. When 'on' the visible portion would just be a small box/space/marker that, when clicked, opened up a larger div with the full note.

I'd tried to do this with the YUI and Dojo editors a couple years ago, but my JS-fu wasn't good enough. I'm possibly better now, and maybe wil try my hand at adding that to this editor (which looks nice for a lot of applications) but someone else with better skills could probably lay the foundation for a 'notes' system much better than me :)
