Yeah AceHeal is very nice. Lightweigth and simple. I tend to rework and change my UI alot and right now im trying a AceHeal / Fubar CurkFu combo. The reason i said GB is the mod that ive used the most and is easier to use for most players and is more of a final product in my opinion. Also Lozareth is still maintaining all his mods. Also it tend to use some more mem and GB optionpane is not load on demand.
What i missed from GB the most was the ability to have a button pop up when someone get diseased, poisoned etc. to quickly cleanse it or need a buff. Now im going to try this CurkFu to do that instead. You can find CorkFu
here. Not that its still a beta.
