Huh. That’s an interesting idea. It’s an extra step to the trash can. And that’s good!
I suppose having this extra step helps with our loss-averse instinct. We have an impulse to hoard, but the Noday/Never list helps us know what we can safely throw away.
The idea of an Archive is to have the thoughts collected for reference somewhere regardless of source. I mark tasks with Rejected (will not do) or Retired (no value anymore, too late) because I find it more expressive than Archived information.
