So, one of the rather annoying bits about Windows 8 is that ‘those that are no longer supposed to be called Metro’ apps all want to suck up your entire screen. Well, I found at least on the Surface running Win8 RT, you can ‘stick’ one app in about 1/3 of your screen leaving the other 2/3′s for other stuff. Helpful way to keep your email visible while cruising the web.
To do this you can use the mouse or touchpad to bring the cursor to the top of the screen and the pointer will change to a hand. Then left click, drag down and to the left or right (whichever side you wish to dock to). If using a touchscreen the same can be accomplished by dragging your finger from the top of the screen down to about the middle (to ‘window’ the app) then slide left or right.
