Currently, if I (or any other player, really) want to read something out loud from a notebook, the entire note has to be removed and read, and then sorted back in. Since (to my knowledge) you can't sort notes individually in your notebook, this means that trying to read the contents of one out loud can really mess up the order of your notebook's contents. I'm sure some people use them as idle scrapbooks with random stuff put in there, but I'm sure at least some people rely on the order of everything for a sense of chronology or incrementation.
It'd be nice if there was a feature or a virtual console command that let you read notes you have selected in your notebook out loud to other players around you, effectively like taking a written paper and using it on yourself.
