In pure BASIC (since Axe is incompatible with the CSE, and I can't find a way to do Asm), I am creating a todo list. This is compatible with monochrome calcs that use .8xp files, meaning the 83+ to the 84+CSE.
It has a monetary system, where you can get points by completing tasks. Use these points, called Sparks, in the Motor Shop to buy customization options, minigames, and more!

►Changelog 1.2.5:
*Actually fixed bug that quits when adding a list item
*Fixed bug that doesn't allow items to be checked off
*Small tweaks

Don't forget, we have some impressive libraries in DoorsCSE now, and they are pretty darned fast.

Looking forward to your progress!

I second this suggestion. Of the DCSE BASIC libraries, it sounds like using ReadLine, ReplaceLine, InsertLine, and DeleteLine to store the to-do items in an AppVar would be a particularly good idea.

Oh, I just realized that I accidentally made a second topic. Could a mod delete this?
