Fantastic component to any joomla installation. I've used it to host my clients invoices securely (saving me having to email them) and it serves that purpose beautifully. Also allows me to host client design work, just like a secure FTP yet I have all the control.
Things I would like to see added, are maybe some theme capability, blue kinda clashes with my design, and maybe options to remove some of the buttons in the client view. Ive disabled some of the more advanced features, and would like to remove the buttons to them.
But none the less, totally worth the money and a must have for any business with a joomla site!
