Essentially each player could have a book in which they store their own information, it could host pictures and text it could also display quest info.

Core concept
This could alow for multiple things such as using pictures for evidence, writing down inventory of say the community bins, allow players to write down things that they personally need to remember like maybe locations. And of course photo sharing without the pain of photo items that could cause lag

Personal twist
A very cool idea would be the ability to store you favorite crafting recipes for less flipping. A more complex add on would be holgraph guides say for example you could put together your ideas for a weapon and the click a button, the click of this button could create holographic trails to exactly the molds you need ore the page you need to flip to in a book. Anyways that’s just my personal thoughts on a player journal
