This application still cannot correctly handle symlinks and cannot run with warnings enabled. It is listed as production/stable on sourceforge, but I would suggest it is more alpha or beta code.
The code is very complex and is not well compartmentalized.
It is not robust about handling error conditions or invalid data and assumes everything will work out.
I would suggest that incorporation of phpMonExploreur or phpFileManager might make this application more robust and more usable.
Currently, it's good for demoing, but I cannot use it for any production environment.
The best thing going for it is the ability to download files directly.
