I have a folder in the everquest 2 directory in the UI folder called ModestaUI. I extract all modifications to that directory.
My current modifications:
EQ2Map Updater
Milquetowst Clock and Compass
MaddBomber Bags
ProfitUI Market Window
Milquetowst Quest Journal
MookHotkey
Milquetowst Experience Bar
Hinton's Guild Window
XUNIXr Knowledge Book
Z Tradeskill with Always On Recipies
Z Heroic Half Size
Insomniac Zoning
Himay Start Bar
Heidrickla's Small Pet
Ariobeth Persona
Milquetowst Infocenter
I install them in this order as well so that some old info does not override the Infocenter's more current info. I have tested the Dragonwulf UI without Ariobeth's Persona window because I thought they may conflict, but I still had the same problem. I have also deleted re-installed all the UI mods with a freshly downloaded Dragonwulf UI last in case I originally had a corrupt download the first time, but no luck.
I notice if I double-click on my paperdoll area where the button should be it pops up my persona window. No other Dragonwulf mods show when I install.
