Hello,
I'm an OmniFocus user, but I wondered if somebody has tried the Hit List
http://www.potionfactory.com/blog/
It looks kinda nice, better than things even, but as long as the other folks don't support Sequential / Parallel projects I won't even bother to try them for more than a few minutes. Escaping the mess of tasks you can't act upon and just display the relevant information is I think OmniFocus advantage.
What do you guys think?
