yeah i have to admit there's some big blocks in that UI that don't go too well with me.
If you need all that on your screen, i would suggest you put a transparent background on your chat window and adjust the transparency of the massive map part on the left to something like 50%.
You'll still see what you need, but you'll see much more landscape as well.
The big jamba frame you can probable reduce as well (font? transparency?) to have is smaller and eat less landscape space.

then again UIs are very personal, if you like it like that, enjoy.
