this looks really good but what I'd really like is for cover maintenance to sync with calibre's book & collections auto maintenance.
i.e. if I delete a book from Sony650 then reconnect to calibre - I'd like the calibre plug in to remove that associated cover from the screen saver set, and when I add books via calibre, for the covers to be automatically added( if I'm within the 15 book limit) - will that be possible at some point ?
Ultimately, I'd like the Sony, when it goes to sleep mode. to use the only cover of the book that I was last reading. that's if is sleeps while in a book, if it sleeps while on main menu than it should cycle all available covers.
finally, please consider upping the 15 book limit to say 50 - there's oodles of space on the sony drive!
