no not at all, dont worry. you go into the settings once and there's a really easy wizard to set gridlines. it gives you big green lines and you move them how you want. then thats it. You just use windows normally but when you want to maximise a window to the nearest grid section you just hold ALT when you press maximise!
ive only got the scren divided in 2, so i open a window and you can just double click the bar at the top while holding ALT to make it fill the nearest section
there's another section to set hot keys for pretty much any of the graphics card options. so ive set one which is for the option in there to rotate the image. again, set it once and thats it. For instance CRTL +F11 on mine makes it rotate 90 degrees, and CRTL +F12 makes it go back to normal
thanks for the comments everyone
