Cool! I had been meaning to try my hand at a to-do app ever since I read "Getting Things Done" a few years ago, and I finally spent a couple weekends on it this month. The tree structure is 100% the way to go, and it's surprisingly uncommon as you note. It's been a fun & educational project so far. It's only SQLite file & some Python functions, no polish whatsoever. Probably will never get to the level of what you have, so hat's off!
