Sounds reasonable. However, I still find it confusing. After all, the name "why" suggests it will tell me why a package is installed. I think this behaviour should be inhibited by default and show a "package is manually installed" note, as it did before. This behaviour could be exhibited by passing the -v flag, which would be used anyway since if I am looking for possible applications that are enhanced by the package, I might as well see them all. -- Saludos, Felipe Sateler
