I took a look at this. Excellent work on his part!
I still use windows and Metro is just forced full screen apps that dont even work with the desktop classic . One thing apple got right was not to mixed iOs with MacOS (or whatever it is you guys call it) - Microsoft once again tried to stuff the kitchen sink into one OS.
I'd actually like to - corny as it sounds - literally just have a smart widows logo floating around. It pops up when I hit the windows button on the keyboard, and it always finds an empty blank spot on the desktop to appear in to be ready.
When i click on it this floting windows logo has literally four flyouts from it that contain a way to access apps, documents, email, and yuch - social feeds. (maybe its configurable so its for settings) - might work well for touch screens too.
Of course these flyouts would be configurable to be a palette of your choice.
Of course I'm not a designer and have terrible ideas - so into the ether with this rant and Prepare for downvote!
