OSX Organize Dock with spaces

Easy way to add spaces to your dock!

Open terminal and run:

defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="spacer-tile";}'</code>

Then restart your dock with the following command:

killall Dock</code>

If you want multiple spaces, you can just run the first command multiple times!
Remove spaces like you would remove any icon from the dock -> drag outside dock or right click and remove from dock :)
