Actually, you're kinda an idiot about the 'Delete Individual Messages' part. That's actually possible. But yeah, we should be able to delete more than one message at a time.
WE SHOULD HAVE A FUNCTION IN MEMECHAT TO DELETE INDIVIDUAL OR ALL MESSAGES; SOMETIMES, WE HAVE USERS THAT WE CHATTED WITH HAD ALREADY DELETED, WE ACCIDENTLY SEND WRONG MESSAGES TO WRONG USERS, WE HAVE TYPOS ETC.
