Add possibility of rename Backup folders. If you have only one computer, it go fine, but if you have more than one, it ends being very confussing. Due iCloud Drive issues, I've changed all of my Macs...
Also I just want to be clear. If a new user install DropBox and enables backup, does this mean that they will automatically be on the beta? Or does the software ask if you want to be on the beta first?
