Supported applications in Lion reduntantly autosave several versions of a document, even if the user does not want to.
Does anybody know how to compare two arbitrary versions and see in what they differ (kind of the old good diff command in Unix)?
Versions is designed to work with any kind of document, not just text, so it's not clear how the "diff" concept would apply. You can of course scroll through the versions and compare them visually.
If yo will click on the name/title of the document (there'll be a small arrow on the right of it), you will get this menu:
You can choose to browse all versions....
Of course it cannot be exactly like diff. I was thinking of something like the "track changes" option (e.g., when you select 2 versions you see the not common portions somehow highlighted).
