Only had a little while to play before patch but I ran into a problem.
My chatwindow didn't work hehe. I can read it but no matter what I did I never managed to conjure up the cursor or the commandline so I could chat. Did I miss something? I tried removing all tabs so I only had one window but it didn't help. If I pressed Enter like I normally do to enter text I never got a cursor and the keyboard was still responding like I hadn't pressed Enter at all. I ended up removing the mainchat xml in order to chat.
Also, would it be possible to incorporate an attack indicator somewhere? Like in the small target strip you have near the chat windows. Make the target name flash or something hehe. With so many spells and whatnot wizzing about it's sometimes bewildering enough just to keep a correct mob targetted, let alone see if I'm actually attacking it.
I know you had a blinking sword in an addon for the old UI but this new target strip is so much nicer and better aligned and whatnot.
/hugs all around for keeping this going
