It's a very unfriendly GUI, for a start. I think a drop down menu with loads of custom things might end up confusing the user because of all the customisations that can be made on this chat, like the sound on incoming members and sound when people live the room; it's not really something that is desirable. The option to change rooms where there is a tab next to the user list doesn't make it simple; it would be easier to have an icon which represents an option, for example if the user wants to go into another room. The fact that you can't change the size of the text makes it difficult for others to read the text properly. I therefore conclude that we should stick with the current chat.
