A thing I have noticed with the graphic tool is that it does not show
libraries. It loks like it pulls libraries when you install an RPM
needing them and that it unin,stalls them when they are no longer
required by another RPM. The only problem is what happens when you
install software who is not in RPM form. Unfortunately it doesn't look
like you can configure that tool in order to tell it I don't want
libraries being automatically cleaned.
Another problem is with those RPMS who are made from translated texts.
I found myself with man pages in Polish and plenty of languages I don't
speak (BTW when I click on "install everything" that should NOT include
man pages, KDE docs or fonts for languages I didn't select) but I could
not uninstall them with the graphic tool since they don't show up.
