GNOME Commander is a fast and powerful graphical file manager for the Gnome desktop environment, it has a “two-pane” interface in the tradition of Norton and Midnight Commander.
I’m sure it’s quite powerful, but as you can see in the screenshot, in the theme that I use for GNOME, GNOME Commander displays some very oversized icons that practically takes the only screenspace available. Which truly puts me off. It isn’t all GNOME Commander’s fault, I think I can just change to a different theme and it won’t have this issue. But it’s definitely not the icon theme’s fault either.
In this light, I do prefer Krusader more, even when working on GNOME. Krusader has a lot more features upon first impression, although some may complain it’s a bit slow. I like the multi-renamer tool on GNOME Commander a bit better tough, since it supports like ID3 and EXIF by default, while Krusader/KRename needs extra plugins (which I’m not sure exists) for those.
