I should have added in my post: this really is a simple app: uses a bit of Javascript/AJAX to basically keep everything on one page. Drag a focus to the top of the focus list and then you just see the todos for that focus. Click on a focus or a todo title to edit in place. Drag and drop todos and focuses to reorder. Edit notes for any todo in place.

Really simple, this took me about 6 hours to code up. (It is a few hundred lines of Ruby with a few HTML templates, and two CSS files, one for browsers and one for cellphones.)
