Topic: Tux Commander (tuxcmd)
Found a file manager, that fits very well into the #! philosophy:
Tux Commander. Beneath a very clean, compact and simple UI it has everything a good file manager needs: 2 panel view, tabs, NC style keyboard shortcuts (F5 copy, F6 move, ...), support for its own mime types, and so on ...
Only thing I'm missing is the keyboard shortcuts to be configurable (but this is the topmost point on the planned features list), and a good default configuration - tuxcmd comes with no predefined mime types at all, so you will have to specify each time you open a file type for the 1st time. (could be solved, of course, if it would be included into #! ...)
Anyways, IMHO this is a great alternative to PcMan, so I wanted you guys to be aware of it - if you love #! and like NC style file managers, this one definitely is for you !
