In general it would be very nice to have "groups" for your messages. I'm not sure if this would display as tabs or what, but it would be nice to have a tab for like "family", one for "friends", and one for "automated messages". that way you don't accidentally send grandma a text at 2am when trying to text your friends. Obviously this would be an optional setting.

If this is unable to be implemented, then another use along the same case would be somehow sorting out non-friends-and-family texts (ex: "Your prescription is ready!", "New hot Deal 20% off!", and generally one-time conversations) from your main feed.
