You know those three colored buttons in the upper left corner of most open app windows in OS X? What do they do? The red button closes the open window. The yellow button minimizes the window and moves it to the Dock. The green button is the so-called ‘zoom’ button and expands the app window downward (usually; sometimes outward) but it doesn’t make the window expand to fill the Mac’s screen. Apple’s usage of the zoom button is not applied consistently.
That’s broken. This fixes it (mostly).
Add the little utility Right Zoom to your Mac and the green button works the way you want. It expands the app window to fill the space between the Dock and the Menubar– and the right and left sides of the screen.
Right Zoom’s preferences are nominal but includes an option for a hotkey to maximize the window from the keyboard.
There’s also an option in preferences to select specific apps where Right Zoom does not change the zoom buttons behavior. The perfect example of that is iTunes where the zoom button minimizes iTunes to a small control panel.
Clean. Simple. Thoughtful. Except for the exceptions.
