I think Apple just needs to review their policy and add another entitlement "Entire Current User Folder ~/" to allow apps that traditionally cannot be sandboxed. I am sure they want us to re-imagine a way for FTP apps to work, but I don't want to change my workflow. I want to be able to browse any folder on my Mac on the left pane. So I won't buy the Mac App Store version. I fully agree with Panic and why they bailed out.
