Ever since moving to Mac a few years ago there has been one App I have been missing, Total Commander. It's not that Total Commander is the most feature reach file manager, but it is by far the most customizable. Ever since than I have been looking for something similar on OS X with no luck.
My ideal file manager would be something like a basic shell, a dual panel file manager with NO functions aside from the common move, delete, rename file, and such. The rest of the functions would be provided through a plugin architecture, like in Sublime Text, for instance.
Does anything like that exist? For OS X or Linux?
