I know this might be difficult to control but I find the biggest annoyance to be skins that don't support my favorite plugins (and vice versa). Would it be possible to create some sort of button template that is universal across all plugins regardless of their functionality?
Example: Reboot's excellent BlueBoot2 and Mountain Lake + My Pictures. No worky worky.
I've had the same issue with other skins as well (some of the TV Guide skins come to mind) but it seems to me that skinning should be a little less cumbersome for both the skinner and end user.
Or do I need to lay off the crack?
