The file-explorer reminded me of the finder in Mac and it works the same way. I started it up and it works in my gnome environment, probably I’ll start using this instead of krusader and nautilus. Or at least try it for a while to get a better opinion about it. I really didn’t get why nobody wrote the columns view in nautilus. Maybe in the next version?
I’m also planning on installing the full KDE4 environment on my laptop to see it working with full bling bling 🙂
