Quote from Seerah*sniff* I came up with the Facade part... :p
If the old version was just "Facade" it would have been 800% better than "Button Facade". I think adding the "Button" part makes it .... bleh ;)
However, I came here to post a small issue.
With the old BF, I was able to "cleanup" what it would not do with the Blizzard skin, in particular when the empty button is shown, the alpha needs to be set to 50% (SetVertexColor(1,1,1,0.5)). After some fiddling I am unable to get Masque to let me set that alpha. The 100% alpha of "Interface\Buttons\UI-Quickslot" is a bit much. Any chance in your hook of SetNormalTexture() that if the default "Blizzard" skin is selected and the empty texture is set that it can also set the alpha to 50%? Then set the alpha of the normal texture back to 100% when "Interface\Buttons\UI-Quickslot2" is set?
