For group conversations, it would be great if you could give the group a name and its own image. Also, allow a shortcut to be made to the group. By this, I mean just like you can put a contact shortcut on the android home screens, a shortcut for a whole group would be awesome. This is a function I had on Go SMS that was quite useful when you part of a group that you need to talk with regularly but don't want to always keep all the messages (for example, a sports team you play on).
