And, if you did not notice, you can manage versions in Google Drive. Why is this awesome? Let's say you have a PDF embedded in a Website. However, you don't want to have to take it down and reload it every time you upload a new PDF. Now, you can simply click on the manage versions box in the far right and upload a new version. It will retain the same URL so you don't have to update your Website! [Mic drop]
On that same note, I've added my favorite "hacks" (including the ones above) into one presentation of the things you didn't know you didn't know Google Apps could do: Google Apps Hacked.
You can check out more Googliciousness on Fennovation.org.
Happy Thursday and try a hack or five today!
