We have divided our 38 gB of Calibre books, documents and audio files into three separate libraries both for function and for ease of backup to Blu-Ray disks. We're using the M-Disk type that are guaranteed for 250 years.

Would it be a BIG issue to extend the web client so a client user could select from any of the "registered" libraries?

I.E. the libraries that show up on the "quick switch" box.

TIA
