Right Zoom utility is created for people who don't like a default behaviour of green Zoom button in Mac OS X programs. This small program changes its behaviour, so a green button will always maximize your windows instead of inconvenient resizing.
The program changes a behaviour of most used applications like Finder, Safari, MS Word/Excel/PowerPoint, Pages, Numbers. Those applications are most annoying examples of inconvenient zoom button behaviour. You can extend the list with your own applications. You can also use Command + Option (alt) + E keys to maximize/restore the current active window in most applications. You can set this Zoom button behaviour for all applications, just edit program options. The program wasn't tested it every possible application, so don't expect it to be ideal.
