Traditionally I’ve always kept my TODO list as a plain text file in my home directory. This approach works, but I’ve been hankering for something a little smarter:
So I’ve had a look at TaskPaper and I’m mighty impressed. Crucially: it is simple. Lightweight markup appeals to the text-editor junkie in me, and the ability to tag items as @done(date) is superb. Of course, I’ve extended the tagging with things like @hours(5) for the purposes of counting and invoicing time. Getting things done, simply.
