Very nice little app! I like the idea of attaching audio.

But there are some weirdnesses that make it hard to use, but they should be easy to fix:

* when I click a note with audio it starts playing, but it does not stop when I click another note that has no audio attached/recorded

* it also does not stop playing the audio track when I delete it (using the little " - " on the upper right)

* it was hard to find out how to delete an attached audio track. it should be possible to right-click the little speaker symbol and choose "delete track" or so

* I just recorded an audio track for a note, deleted it and recorded something new. But it's not possible to record something new! The old audio track comes back every time (instead of the new one)!

I really like Memento much, much better than Stickies, and I am considering buying it... It would be much more professional with the audio features fixed.
