[@Lady Amalthea] Hmm, mass-moving to trash sounds reasonable since deletion is pretty extreme.

And since trash is really just a folder, you still get notifications. Though the difference between "Trash" and "Delete" is probably very unclear.

Do you have any other ideas for a fix to your scenario? I should've made it clear that once you delete a convo, you will not get notified about future correspondence. 

What about on the sender's side? If Lady Amalthea starts a convo with me and I delete the convo, then Lady Amalthea will only see herself in the participants' list. I suppose I should broadcast more clearly that Mahz left the convo and he will not receive a notification or be able to read it? The sender could unknowingly start talking to their self without a receiver.
