Because sometimes things are just a bit done!
Doing It is the only to-do list that allows you to keep track of how done things are! Life isnt black and white and nor is Doing It. Create an item to do, select a tag, due date then track your progress.
Things might not get ticked of the list - but at least you can see some progress!
