Hi! I'm Mike, one of Power8 developers.
DoMiN8ToR, thanks for the review and good words on Power8!
Basically, no. It was developed for Win8, just a screenshot was taken under W7. At the moment, project page already contains Win8 screenshot, take a look.
BTW, don't compare us to "ClassicShell". We offer similar functionality, but different philosophy lies beneath. We can discuss this later on the forum pages.
