how about qtodo ?
I think qtodo has even more features.
- it can use deadlines
- use different lists, open them at the same time
- use "priority", "status", ...
- filter options (on status, priority, deadline, text in the items)
- nice layout (custom colors and fonts)
- icon in the systray
- ...
All this in a 0.1 release !
Have fun,
Chero.
