I like the uses search idea. It would make finding the user you want to find easier, instead of just looking through the threads to find it. Also, more emojis, colors, fonts, etc would be a nice detail.
About the more sections to post idea, it think the sections we have right now are more than enough. We don't want to make the LM forums look like a posting section labyrinth, but I like its purpose.
