Basically when there's a group chat I don't want to miss out on the chats going on in it but I don't want my phone vibrating 100 times a minute and I don't want a notification all the time either. Pretty much what I'm suggesting is an option where once you've read a chat, it will allow 3 messages to come through as a notification on your phone but won't notify you of any others until you read the chat again, that way I still know that something happened in the chat but my phone isn't being spammed with vibrations. I know Discord does something like this and I think it is nice.
