I started using Bento (now on version 3) to organize my case work, but I've now moved beyond that, and use it to organize every part of my life. I call it Life Central.

Here's the To Do library shown in the Journal library above:
Just about every library links to all the other libraries. I start out the day with the Journal and move to the other libraries as needed.
