Hello!
Without doubt, my favourite power to use on XAT is the PCBack power. I really like my PCback and I think it's just a shame that I don't get to see it when I open a chat, only the people I'm talking to can see it. I think this should change. I would like the ability to see my own PCback when I'm private chatting someone who doesn't have their own. In theory, if you have a PCback but the person you are chatting to does not, you should be able to see your own background as opposed to the Main Chat background.
I've spoken to several people who have also wholeheartedly agreed with my suggestion and I'd like to see it completed soon. So go on you cute lil XAT staff in your tight jeans and cute shirts, make my day - Add my idea.
