Summertop: Not really about the rich text editor - since I have mine off unless I need it - since I don't write "fancy" messages often.

But to expand on your #2 - one of my suggestions from a long time ago which I will repeat here is an option to have the submit button ABOVE the game board. On games like battleboats where there are multiply boards, it takes extra scrolling down to find the submit button, and would be much easier if they were also a set above the game board (leaving a set below the game board with the message box in case want to write a message - and of course, just an option since some will not like to see if above the game board)
