This thing crashed my dock. My files were not erased thankfully, but I did have to put my dock apps back and that was a pain to find it all again. i found out a better way to create space for your dock and there are no downloads for this. If you have A mac os x, go to search and type in applications and click on it. Keep that open and go to finder. On finder, search utilities and drag your apps from your dock into it or search it with the applications folder that you opened. Put utilities app on your dock { utilities comes with any Mac OS X } and click on it to open up your apps. It worked for me well and kept my apps in a more quick reach location. Do not download Dock Spaces! What a pain this thing was.
Best:
It was easy to download and is great if you get it to work correctly. Easy to download and is free
Worst:
Can cause your dock apps to be erased when you do not want them to. It does not always work correctly. Not worth the download. Pointless. Confusing and difficult to use.
