Revamp the entire private messaging system (Not like Facebook -_-)
I believe the messaging system needs a complete makeover, as it is highly unreliable these days. I suggest you keep the same framework that you have now in mind. I do not like the idea of having a teeny tiny Facebook style chat in the corner. I would like to see a more enhanced version of what is already available now(: With more sharing options for pictures, gifs, albums, and videos etc. Oh and perhaps a subtle sound for when the chat window is already open and a new message is received.. Just some thoughts :3
it is nice when sounds can be turned off, like in a checkbox saying '''mute sound''' or something..
on the sharing picture via message especially and sound
