I think it would be nice to be able to submit art and literature to worlds as well as characters. It would be nice to have all the art/lit done in the world available to view all in one place.
+1. Having a world gallery could be useful for sticking stuff like, say you want a map? You can post it to the world gallery without having to submit it to a character or offsite.
+1 would be very useful for people who don't use worlds as groups/use worlds as an info dump. Also want to pitch the idea of worlds having tabs too for organizing lore, group rules, misc. info, etc.
+1 some way to have a directory of fics belonging to certain plot could be handy for people with multiple plots and AU’s.
