Pin Desktop Apps To The Start Screen
If you like the new Start screen, but you just want to use it as a hub and do all the rest of your work in Desktop mode, you can use it as, basically, a fancy app launcher, widget hub (with Live Tiles), and favourites hub by yanking out all of the tiles that would open a separate Live app. You do this just by right-clicking a desktop app and selecting Pin to Start.
This is a good tip to use in conjunction with picking new default non-Modern apps. You can also keep just one or two Live apps there, and use them as your Snap apps. That will also have the added bonus of making the fast-swap gesture more usable since it would always be the same thing
