OS X Lion comes with some pretty handy features, and the System Preferences window can soon become full of things you don’t really need to refer to all the time. Luckily the developers over at Apple have this covered. Somewhat of a hidden feature allows you to hide/show preference panes, with just a few clicks of your mouse/track pad.
To do this launch your System Preference Window, which can you find under Finder > Applications.
Once launched click on the ‘View’ menu in the menu bar at the top of your screen, and select the customise option.
Each preference pane will then get a ‘tick box’ just to the right of it’s icon. Clearing the tick in this box will hide it from view in the preference pane window.
If you change your mind at any point, all you need to do is repeat the process and tick the ones you removed.
It really is as simple as that.
