I stumbled across this technique that may especially appeal to developers with multiple windows. Usually I struggle with switching windows and seem to be constantly resizing to prevent overlap.
Open at least four windows then right-click on the Task-bar and select "Show windows side by side".
Image shows seven windows open side-by-side using two monitors.
Notice the small margin above each window. Dragging any title bar to the screen top opens the window in full screen. Using the F11 key also displays full screen.
To revert to the "side by side" display, drag the title bar slightly down or once again use the F11 key. The screen will immediately pop back into place.
If you use Windows, give it a whirl. If it does not work then please specify your windows version.
