Online Calibre Management
I use calibre-server to host my family's "ebookshelf" website. I would be very interested in a plugin that would enable a password-protected Calibre management area that would allow me to login and upload ebooks, edit metadata, start conversions, etc.
Now I either have to be sitting at the server machine, remoting into the desktop, or using ssh and the command line options. None of these is optimal.
