I was looking for a maximize solution on my Mac that felt more like, well, Windows. RightZoom (almost) gets it.

Best feature: keyboard shortcut. I can just mash down on Ctrl+Alt+Command+M and maximize a window. Boom. Awesome. (See below.)

Worst issue: causes weirdness of windows when I'm multi-mon. Only on my smaller window, which is fine.

Check it out.
