The UI in FF14 is fairly well designed but it's definitely missing some features that it should have. So, i thought i'd suggest a few.

-PARTY MENU
-Ability to change the way the gradient faces
-Different-color gradient backgrounds behind players of certain roles (Green=Tank,
Red=DPS, etc et)
-Colored HP/MP bars (Just blue can get boring!)

-PARAMETER BARS
-Ability to seperate each part of the Parameter bar apart- HP/MP/TP, Targeting mode, "Friendly" icon
-Change colors of HP/MP/TP bars (Red mana is just weird.)
-Change font size of HP/MP/TP amounts

This'll continue in another post. Because character limits, why not.
