The PE Information expert is not new, it has been part of GExperts for many years (I remember using it in the 1990ies). But I have extended it to show some more information:
Version Information
Pretty standard but still: I was missing it.
Package Information
Nothing really fancy, basically it is all available via Delphi RTL functions, but nobody had yet bothered to add it:
Package Description
Units Contained in the Package
Required Packages
Exported Classes
This one is based on Ondrej Kelle‘s answer on StackOverflow.
