Hello Nikecmh
I will maybe release a little patch for the 1600*1200 version.
In fact I think that making the Journal active quest resizable will allow you to play with his size and the size of the secondary chat window to have it for 1600. For the bottom, using 6 one lines Hotkey bar instead of 3 double lines hotkey bar plus playing with the mainchat size can make something for 1600.
If you are interesting in it , I will check for that
