What's a good "todo" widget for Mac OS X 10.6? I'm considering small widgets like QuickCal, Anxiety, DoBeDo, etc.  Integration with Mail/iCal would be great.  What's your favorite?
Lately, I've became really passionate about Alarms.

It transforms your entire menu bar into a drop-area for whatever file, email, shortcut you want to handle later.

Plus, it syncs with iCal, so you may use it in combination with another full-featured app (like TheHitList).
