Well, it would need a widget - to start with - so that a quick overview of the tasks could be presented on a desktop. The e-mail widget that comes with Maemo is a good example; another is the Calendar Home Widget.

The widget would need to be functional - i.e. not a static fill-the-entire-screen thing like the GPE Todo widget; it would need to be resizeable, and of course have fonts that could be adjusted (down, preferably).

Your taste may vary, of course
