It´s a pity that the trial version of WB doesn´t support third (fourth, fifth or whatever) party skins completely. I mean the WB skins from skinners out there. Not everybody is impressed by a dragon spitting fire, although it is done extremely well and shows the potential of WB.
But there are many potential users/customers, which just want to test a skin that´s out there, which they love from the preview. But what they get is a broken version with no alpha blending and no support for e.g. color variations. And are - understandably - disappointed.
I am speaking for minimalists (as I am one) which never can understand the potential of WB also for this category*, if they haven´t bought WB (like me) ...
*: I have tested Visual Styles today and it was so disappointing compared to WB...
