AAH Can you explain this comment?
Uninstaller seems to take the "snapshot now, install, snapshot then" approach -- anything changed between snapshots is obviously new. What it will obviously miss is anything changed after the second snapshot -- and if it doesn't actually *do* a second snapshot, you're in even worse luck, since every change since the initial installation is marked as a new file (correct me if I'm wrong, please).
AppZapper takes a programmatic approach -- potentially imperfect, but also potentially perfect, and in either case *much* faster than the Uninstaller approach.
