I passed by a Linux command-line tool for displaying and easily navigating the files/folders on a GUI-like user interface some time ago, but I can't remember the name of the command.
The background color was blue (like the edit tool in Windows Command Prompt) and it was easy to navigate between files and move/copy them, and even edit them.
Is it a builtin tool for all Linux/Unix systems, or does any specific version of Linux support the tool?
Did you try Midnight Commander ? From your description it looks like it might fit the bill.
