I use the Vert UI mod
I modified the Wis caster self box, to accomidate WIS AC ATK under the icons
I changed the way the bags were handled having the first four show up, instead of the randomness he has in the basic layout.
I changed the armor slots on the right side to better suit my right click items, to make it easier to just open a bag click earring, close bag.
I used a no title chat box for all my chats.
Nothing hard really, as I have never programmed in xml before.
