I'm now an Ubuntu user for several years but a friend of mine has Kubuntu installed and although I'm no fan of KDE i really liked the file Browser "Dolphin". Especially the Mac OSX like "columns design" with the preview at the right side. Like here http://img23.imageshack.us/img23/7531/screenshotlibevent004do.png.
Are there any simple solutions to get this design in nautilus - my search wasn't very productive till now. Usually there is no alternative to installing a new file broswer, but I'm not sure if its worth it.
Does anybody use Dolphin or anything similar under Ubuntu and could share some thoughts?
