Adding Separator Spaces to the Dock in Mac OS X

I'm a fan of organization... most of the time. Using my Mac provided by work is definitely one of those times where being organized is key. Sometimes there's some applications you can't live without, but they may not be related to the overall use of the machine (personal apps on a work machine, for example), so having a quick visual way to separate the apps is very useful. Below is how you can add separator block to your dock.

• Open a Terminal window on your Mac.
• Input the following line, then press Enter: defaults write com.apple.dock persistent-apps -array-add '{tile-data={}; tile-type="spacer-tile";}'
• Input the following line, then press Enter: killall Dock

This will add a new blank space to the right-side of your Dock that you are able to drag and drop wherever is needed. You can run this as many times as needed to add multiple spacers as well!
