The internal messaging needs a good overhaul. I'd like to be able to add users to a message without having to create a group in setup. Basically messaging needs to work just like it does in 99% of all other messaging apps/phone.

The notifications also don't behave as one would expect. I receive two pop-ups when I get a message. I just need one notification where I can click anywhere on that notification and it will open the full messaging box. I do NOT need a window where I can't see the full conversation thread.
