Not Loving 5.0.5

I've been a big fan and user of Prezi for the last two years. Every update has added something new and useful - until now. With 5.0.5 I've lost the ability to "Save As" versions of my prezi's using the Mac desktop client, and I find the new UI for viewing local and cloud version of my prezi's confusing. It's weird that I have to import local prezi's into the new UI when everything is still on my hard drive. I had to shorten the file names, because the new UI truncates the names - and I append with version numbers or dates. It's weird that when I have a local copy of a prezi and upload it to prezi.com, it disappears from the new UI screen and I have to "reimport" it again from my hard drive.

Please restore the ability to duplicate or "save as" prezi's and fix the multitude of problems with the new prezi UI for accessing and posting my presentations. Thanks.
