Projekt, a popular Symbian OS outliner, is being ported to S60 3rd Edition. Asri al-Baker has been beta testing it and some screenshots are shown below. With Projekt, you can manage your lists, todos, mindmaps and shopping lists.

"This is the very early beta and surprisingly, most of it's core functions worked very well. Things like adding notes, creating new lists, as well as some keypad shortcuts are already implemented. I'm impressed!"
