One of the great features of SkinStudio 5 was the ability to directly import XP .msstyle themes and convert them into WindowBlinds skins, giving you access to the many .msstyle themes out there, but allowing you to retain the ease and power of using WindowBlinds. Unfortunately, that feature isn't present in SkinStudio 6. But never fear, there is actually a free, stand-alone tool to do just that!
