The taskwarrior website has pretty bad navigation between pages, but there are some gems to be found.
One is a wrapper script called tasksh, which is used for reviewing tasks. It basically uses a tagging and timestamping system to put your tasks in a review queue, so as you add things and push them off nothing gets lost or stays around longer than it needs.
I only have a few days of tasks, but I’ve already been wait-ing and setting due dates that put them in the future, and some are already done that I haven’t checked. So this is a useful utility!
