There are certainly more pressing issues to take care of before considering this one, but it's always good to have things on the horizon:
Nowadays it is possible to convert images and even videos in surprisingly good quality for viewing in a terminal. This should be taken advantage of in order to optionally include previews of attachments in the message section (for videos, one should just show a single frame as a picture).
As a side effect, this feature would certainly attract lots of new users (whether that's good or bad is up to you to decide).
