This was literally my immediate reaction as well. You could further simplify the concept by just asking, What’s next? And other todo apps have done this.

Still, I like the aim!

Back when I was invested into todo lists and the Android task list app I was using was still available (since archived by the author):

01 Today

02 Soon

03 Month

04 Scheduled

05 Later

09 Cancelled

other tasks lists like "1 SuperImportantProject", "9 Someproject".

Then discipline to recycle your lists, and force yourself to stay on list.

The key app features required: 1) multiselect and move between task lists, 2) easy, low friction task creation, 3) calendar and task integration for scheduled tasks

This. A grouped agenda style would be really good, if it can handle repeated entries properly. On Android I exclusively use agenda mode but it's quite cluttered with recurring events.

It is a demo of month, as demo font was used for graphics :)
