My list of to-be-packaged libraries in the web facet / "Modules and Libraries to Package" is quite long. My web module depends on some library modules, which in turn depend on other modules, etc. Quite often this list contains duplicate libraries. Sometimes I see old/obsolete versions of some libraries. However, there seems to be no easy way to figure out from which dependent module a given library is "inherited". I don't know what a good UI would be. An additional table column in a possibility, but I'm not sure if this information is "valuable" enough to always take up screen real estate. Perhaps a tooltip would be enough?
