I’m not sure how much this would bring to the game, but I think it would be a nice addition. Similar to what you can do from this website, you could view reputation, items, emissary stuff, friends. It could also include features for quests eg. maps for gold hoarders voyages.
There are many features, like a map, which would be really helpful but I think it may have to be limited as it would take away from the realism of the game as otherwise there is no point looking at the map in game.
Open to discussion if interested :)
