Update is inconvenient! Give us back the ability to manage .pez files!

I manage all of my files the same way - in my folder system in Finder. With the new Prezi Desktop update, there is no"Save as" feature, Meaning I can no longer use my folder system to manage my Prezi files, even as a subscriber to the Prezi professional product. I have over a dozen different clients, and there's no way that I can keep all of my files straight if I cannot use my Finder folder system.

Please bring back the option of saving Prezi files as .pez.
