* Settings in admin needs to be cleaner.
* Maybe a button of some sort to turn on/off a "chime" for new messages.
And, my two biggest issues are these:
* If you reload the page entirely, you see the last 10 messages. Which is fine; however, I wish that I could either set a fixed height (vert scrollbar when necessary) and/or set how many messages will stay on the page without reloading. I don't like how it continues to grow and grow until you reload the whole page. (Sorry, I tried setting the 'height' in the css file, but it never seemed to care about that).
* My other big issue for improvement is color coding "Guests" (who put in their own name so they could pretend to be another user) from "Registered" users. Like Blue for registered and green for guests. That'd be a nice add; that or have a prefix added to their name.
However all in all, this is a great mod/com!
