The only thing preventing me from rating XFCE a 10 is the file manager. It has some quirks. Still, this is an extremely impressive project.
Excepting the file manager everything about this project is perfect!
If the fm "go to" would act more like bash that would be a start. It only seems to remember directories it has been to. Also, sometimes when you look at a directory with images it makes a huge space between the thumbnail and the name requiring you to scroll left and right to see everything. Moving or copying multiple files doesn't seem possible.
Also, more keyboard shortcuts would be nice and a way to configure them (gimp style would be amazing). In fact if it were done as a library it would be possible for many programs to have such a handy feature.
The fm isn't that big of an issue for me as I just use the terminal. But if it were improved in such ways I might be inticed into using it.
