There are several Mac programs that, once you click their green Zoom button, they don't go in full-screen mode. Instead, the windows are resized based on what Apple thinks is the best fit. Right Zoom is an application that helps you get rid of this issue by maximizing any window within your desktop to full-screen mode.
Once you launch the app, you'll have access to a Configure window where you can set up the program. There, you can define a global hotkey for immediately toggling full-screen mode, activate Right Zoom app, and choose for which apps to enable the zoom option and the ones to be left unaffected.
Another good aspect is that it uses a very small amount of CPU resources while running in the background.
The only bad thing that I have to say about this program is the fact that on its Configure window it displays annoying ads. Nevertheless, this app is a background process utility so you won't get to see the Configure window much, you set the options accordingly and close it.
All in all, I'd say it's worth installing this program on your computer as long as you're tired of the imprecise behavior of the green Zoom button on your Mac. On the other hand, you can drag the margins of the windows to their maximum length and height.
