Your system of recopying the previous day's list, reordering, adding new items, and I assume removing any done or stale items, is very close to the Bullet Journal [1] system that I have started to use since last year.

It's interesting to see that you came up with a similar system.

It really is an excellent system that keeps me organized and sane during the hectic periods of life and work.
