[@Lady Amalthea] Okay, good idea.

I replaced mass-delete with a mass-move feature. You must move stuff you want to delete into the Trash folder and then use the "Delete All Trash" button to erase it.

Oh yeah, and I can undo all deletions. If you've accidentally deleted something, just let me know. But I'm gonna undo *all* of them.

I still need to improve the sender side if everyone in the convo has left except for you and you end up talking to yourself...
