Something that would help me a bit with my HUD would be the ability to change how things are aligned and justified. Even the ability to rotate.
I play on 3 screens so being able to switch Left/Right Justification of the Duty List would be a big help.
Also, a way to switch:
HP=== MP=== TP===
to:
HP===
MP===
TP===

Also a way to choose how lists grow, such as: putting party list on the bottom of the screen and having it go up as you get new members rather than down. Same thing for Duty List.
