Yojimbo users

Not a regular user but have been trying it out and while I do find it useful, I have also found it to be somewhat awkward to use as I see fit.

Problems I have found (or to which I do not know the solution):
Can't drag an images on to the side of the screen thing only as the content of a new note.
Can't add to a custom collection from the quick add F8 thing.
Can't automatically label note when adding to collections.

So far I have found it just limiting enough to be annoying but just useful enough to warrant the effort to keep evaluating. Right now, I don't think it is worth the asking price in it's current state but I'll wait a bit longer before deciding.
