UselessMemo for Mac

From TripuzSoft:

How often, while browsing the web, or while working on word processors or on spreadsheets, do you need a place to write notes, to paste text, or things like that?
UselessMemo can do all of this for you!
It's a light and neat software you can use to keep notes, write texts, etc.
You don't even need to save, since it automatically saves the text, and it constantly floats over the other applications, so that you can always have it ready.
And it's even optimized for Mac OS X 10.2, with a cool brushed metal UI!
