I know about facilitating serendipitous discovery, but I'd also be interested in seeing this implemented for books and collections. Why? Well, for example, I have a collection called sermons, and would often like to read one at random. Or I might want to test a hypothesis about a common Greek word in the NT and wanted NA27 to open to a random place to analyse the Greek.
I thought such functionality would be fun and hopefully not too much coding (assuming it's not there already and I've not missed it, which is quite possible!
)
