453 minor: Comparison labelling
In case it is unintentional, note that some say 'file' and others don't e.g. Compare file size v. Compare timestamps

And some are plural, other's not e.g. Compare contents v. Compare file size.

Also, I suggest s/Compare timestamps/Compare Modified/ so to be more specific and be consistent with the folder lists.
