piles develop on top of the bins

The basic insight here is putting some kind of box around the pile improves organization.

Sorry if this is a super neurovanilla question, but isn't that what your dresser drawers are for?

I try for years to implement a "do later" box in my it support team. If you don't have time to put something in a proper place, drop it in the do later box and once in a while get it sorted.

Idk what it is, maybe neurotypicals just don't get it.
