Maximising windows using Snap
You are probably used to double-clicking on the title bar of a programme to maximise it. Now try dragging a window to the top of the screen to do the same thing.
Drag a window over to the side of the screen to it will resize to half the screen. This is useful for positioning two window side by side.
