Fast, just want Breadcrumbs, and a option to show thumbnails sidebar like windows. Overall the best "nix" file manager and its fast.
I did really like the old 0.5 releases. But the new rewritten sucks. Sure its still same fast, but many useful functionality is just gone (forever?). I do miss the folder tree view, without it, a filemanager is useless. I switched to Dolphin, on my new Laptop there's no big noticeable slowdown anyway. Please dont go the Gnome way! We arent all that stupid, keep functionality, flexibility & power.
Version 1.2 has removed the "Open folder as root", that is one of the features i used every day. And there is no option to re-enable it, as people asked in user mailing lists and on launchpad. Losing an important feature in an upgrade, with no replacement is always a symptom of bad design.
