I know player journals are on the roadmap for future features. I'd have to dig back through some of the earliest comments, but I seem to recall a discussion about collaborative GM capability as well. If you put the two together (sort of), you end up with the idea that players can add content (definitely need some way to easily identify it as being "non-canon", etc.). Such information would automatically be shared with the creating character, but then I expect it should only be shared further by the GM.
This sounds like a feature that could be very valuable. Would you mind spending some time fleshing out what you think would be helpful to add (or to exclude - some players I know would lobby for auto-reveal any snippet that includes "pp" for instance
)? The rest of us can then weigh in and to refine it and make additional suggestions, so when Lone Wolf has time to start adding new features we've got something fairly detailed that there's documented desire for.
