I'm mostly interested in general use annotations. Basically, I want the ability to quickly circle a feature in a plot and point to it with an arrow associated with a text box with some explanation. I think the mini, floating blocks as you described could work well as long as they can be grouped and "locked" in place so they don't accidently get pushed away. OneNote has the ability to add such general annotations very easily, but there's no ability to lock the positions, and so as a result notebooks can easily become a jumbled mess.

Sounds good, I'll work on adding comments and annotations (that can lock in place) and update you when that happens.
