I think these may just be the limitations of it being a 1.0 release. The Windows version has all of these features.
The UI looks great though - if only office for mac proper could follow with the same quality, it would be great.
However, I can't figure out how to retrieve a .one file from the Mac Client to check for the format - anybody knows where it stores its file locally ?

Any sandboxed app has its data under ~/Library/Containers/<app>, then from that usually under the Data/Library folder, which is a kind of mirror of your user library folder, just holding that stuff the sandboxed app is allowed to see.
