Love the UI. I can't find anything to make it better than it is right now.
I like how you put the implied target on top of the target window and gave it an angled corner, makes the whole UI flow nicely as one. If you can stand leaving the text size at 15, you can take the secondary chat window and shrink it up to where the bottom of the chat lines up perfectly with the clock window. That's what I did and then added the compass underneath that and it looks great. I love it.
