It would be nice to see an option to have each contact's notification icon automatically change to match my SMS/MMS thread with them in the app. I appreciate that you are able to manually change this setting, especially on a person-to-person basis, but it's a bit obnoxious to have to manually choose the color for every person. I would suggest making it an optional toggle in the settings, as some people don't like to have a rainbow-colored notification bar
