Preview's new annotations features are awesome. I'm finally able to read on my computer and make notes in an easy way. This is all good. Except that there apparently is no auto-save feature in Preview. I was working on a PDF and had lots of notes and then accidentally hit the keyboard shortcut for "Move selected PDF to Trash" (this, IMO, should not even exist, or at least should be something more complicated than command+delete or, at the very least, have a confirmation of deletion window). Anyway, once I moved the PDF back to its original file location and opened it back up, all the notes (lots of them) that had been added before the last save were now gone. I'm stupid, I know. Anyone know of anyway that I might be able to recover my changes from some temp file stored somewhere or something? Oh, and when I select File>Open Recent, it's always empty. Not sure why, not an option in Preview Preferences. Thanks.
