I've been an advocate for the cloud environment but...
The other day one of my colleagues moved some folders using the web interface. Once it informed him they were moved, he walked over to my workstation to inform me of the changes. I started browsing the new location in Fusion and the files started disappearing before my eyes before the whole folder was gone. All said, I'm now missing what I believe is 40-50 files. We've got a call in with support but, now starting on day 3 these files are still missing.
Services like Dropbox have a way to go in and undelete files/undo changes. This would be really freakin handy. It would also be nice if there was a way to go in and quickly select entire projects or all projects and create an archive one could save locally. Lastly it should be a lot easier to, in events like this, get a backup from your end.
