Layouts options allow you to manage existing applications windows setting their position on screen and closing them.
Quick Layouts and Quick Layout Shortcuts give you ability to quickly move and resize the window to fill the full screen or half of the screen exactly.
Just drag any resizable window to the left edge of the screen with Quick Layouts enabled!
Double click to Zoom enables addition functionality of double click on window’s title bar.
Note that it is only enabled if you do not use double click on title bar to minimize. This can be checked at Appearance pane in System Preferences.
Real Zoom enables additional behavior of the green Zoom button of any window. Right click on it to maximize the given window to the full screen.
E.g. Safari zooms its window to website optimized maximum size, which is not always what you prefer. With Real Zoom, you can use both system zoom by left click on the zoom button and Real Zoom by right click on the zoom button.
Real Close enables additional behavior of the red Close button of any window. Right click on it will quit the whole application immediately.
Usually in Mac OS X the close button closes only the active window of an application. Using Real Close, you can quit the application by right click on a close button of one of its windows.
