This piece of Mac software instantly catches my interest with a simple idea I’ve yet to see in other ToDo list managers.
Not only does DoIt [formerly ToDo] categorize your tasks, set with priorities and deadlines; it also associates each todo with a URL, address book contact or file on your computer.
Compatible with Applescripts, Quicksilver and iCal, DoIt also adds a sync function across multiple computers using .Mac – got all bases covered.
