Presently UI has ‘choose disappearing messages’ that becomes a notified global setting for a chat. UI enhancement would be right click/tap&hold on send, and choose normal send, or disappearing send.
disappearing send could turn on, send, and turn off afterwards?
not sure if this is possible ? but would make ephemeral messages a lot cleaner:
“does this look like the right can of soup for dinner” would be handy to autoremove from all chats after 24hrs and keep the app storage smaller, even if the “directions to dinner” would want to be held long term.
