Yeah I hated dolphin at first, but I've managed to get it set up pretty much like the old midnight commander Konqueror profile, complete with tree view and terminal, specific settings for each folder.
I find the interface pretty Mac-y, not very functional without first having a good look in all the corners and submenus, to find the settings and keystrokes. It's kinda got the 'my first browser' settings as defaults. Getting used to the + and - icon selection method has led to a few hiccups!
So I've got Dolphin pretty much running OK for my basic uses now, just need a few more of them open then Konqueror3
