Please could we have [Windows Key] + <folder path> [Return] work as per Windows 7 (i.e. launch Explorer at that path).
Loving Start8 and plugging you guys in the Windows Subreddit.
Assuming you mean winkey + \windows + enter opening the windows directory then I am pleased to say this is implemented in our internal builds.
It should be enabled in the next beta release which should be released later this month.
