We LOVE the "Remind Me" button for Posts and would like to see it available for chats as well. Quite often we'll see a chat that requires action but we can't take action at the very moment (whether on our mobile or desktop). Currently the only way to remind ourselves about that chat is to promote it to a post and then set a reminder.
Currently it's still much better for us to email co-workers something that is actionable because it will remain in their inbox until they actively delete archive it. If we could set a reminder from a chat it would solve that problem (of course we'd like to be able to decide when to remind us on a chat per chat basis and I see this as another topic in these forums).
