Can you restore my deleted pms? I deleted a couple by accident.

Yeah, in the short term, I'll make an "Undelete Everything" button. Unfortunately that means you'll have to re-delete everything except for the convos you accidentally deleted. I can do this today.

In the medium term, I'll add some sort of graveyard UI that lets you undelete individual convos.
