This is tangentially related to the Treo. Perhaps only because I keep a to-do list on my treo.

I like the palm desktop software, but it it a little large to keep up on the screen as I work.

Has anybody seen or heard of software that puts your to-do list as a small post-it note sized window on the edge of your screen?

Preferably something that can be integrated into palm desktop or something. Other than "Use duct tape to stick your treo to the side of your monitor".
