My whole calibre library would put me over my free Dropbox limit and I usually only ever want a select group of books I've marked as prioritized to be synced into my Dropbox so I can save it locally to my phone. Syncing only this subset also makes picking books I want easier on the phone because I can't sort/filter in the Dropbox app like I can in Calibre so I don't want my non-prioritized books there at all.

I can manually switch the virtual library and manually copy those to a new library and manually redo this every time something changes but I'd prefer an automated way.

One way I could see a plugin doing this is to grab the books from Calibre based on user's criteria, then create a folder of symlinks to each of those books in the Dropbox folder (thus data never needs to get duplicated). Would this work?
