The UI customisation is quite handy and allows you to move around windows, for instance the Mission Tracker... you could move it to the left side of the screen (which some of us, silly as we are, would like) but you CAN'T make the mission text align to the left so that kinda nullifies of option of moving it there in the first place. It's been asked before and it's still not in. Adding the option to flip text alignment for the mission tracker (only one where it makes sense really) is very much needed.
