Everyone knows that multitasking is usually bad for your productivity, and that in order to get ‘in the flow’ one would need to focus on the task at hand and nothing more. Having your app maximized to your screen size might be enough most of the times, but a real full-screen mode(that is, covering also the Dock and the MenuBar) would be even better.
Apparently the next operating system version for your Mac(OSX Lion) will add native support for full-screen apps. But until then, neither of these two options are made easy by the current Mac OSX version.
If you’re in the same place as I am and too impatient to wait for your full-screen productivity boost, I found a temporary solution. An awesome one which, best of all, is completely free(although donations to their developers are welcome)!
