I agree that I am not quite as happy with KDE 4 as I was with KDE 3.5. And I agree that Konqueror is the best file manager I have ever seen and I don't like Dolphin (perhaps because it's just not Konqueror). But the KDE team has done good things in the past and I am sure they will focus more on stability, usability and configurability. I am clueless how to do many things in the new System Settings utility. Perhaps the KDE team will post a few videos on Youtube showing how to do various functions.
I have heard that there were some compelling reasons for KDE to a major rewrite but do not know what they are. Is there an article that (briefly) discusses the reasons? Thanks, Paul
