Thanks for the response, AzDude, but I already saw that video and it doesn't help. As I said, I'm looking for a manual or guide with instructions and explanations, not a marketing trailer.
How does Tiles fit in with Windows Task View and the Windows Task Bar?
How is Tiles intended to be used?
What are the tabs in the Tiles bar for, and how are they used?
How are windows added to the Tiles bar?
How are different desktops added to Tiles?
How are desktops accessed or switched from Tiles?
It looks interesting and useful, but I can't get started with it.
