Developer Alex Arena has come up with a handy tool (more like 27 handy tools) that put pref-pane shortcuts in your Dock. Next time you want to adjust your audio, just click the Sound icon down there.
Preferences Quick Launch is a free download which includes a set of 27 small applications, each containing instructions to launch a certain preference pane for you.
For instance, if you like to change your wallpaper on a daily basis, simply drop the Desktop & Screen Saver System Preferences pane in the Dock or in Launchpad. It’ll always be there to serve you just a click away.
As it’s generally the case, Alex worked up this neat little gimmick as a solution for his own needs. When he saw how convenient his invention was, he decided to extend it to all pref-panes and offer it to everyone for free.
I don’t recall seeing a donations button on his site, but I’m sure a lot of OS X aficionados would love to compensate the guy for his good deed. Preferences Quick Launch majorly awesome!
