Just change the file you want to use to: EQUI_PlayerWindow.xml for them to work.
*EQUI_PlayerWindow_stam.xml
Tweaked Version of my original EQUI_PlayerWindow.xml for the Mix and Match Set triness.zip. Changed out AC/ATK with Weight, Traded positions of HP and Weight.
*EQUI_PlayerWindow_mana.xml
Tweaked Version of EQUI_PlayerWindow_stam.xml. Changed out the Fatigue/Sta loss bar with a Mana bar, added percents.
Special Thanks to Shadowcross for letting me use his UI and tweak it.
(not sure where the original version came from)
