Currently only one of each of a couple types of articles can be linked to a map marker. I like linking Plot articles to map markers to keep track of what quests have to do with which places. Currently, I can only link one Plot article per marker. Some locations have multiple separate quests happening there and I have to choose only one to be visible in the pop up.
Allow multiple articles to be linked (see images). This allows users of the map to quickly find the quests tied to locations on the map. It would be beneficial to also be able to reorder them.
My example of linking multiple quests or plots is merely my main reason for this, but this would allow lots of options to all sorts of uses. Maybe there's a marker on the map for a town which has a prominent academy and two competing factions. With this feature you could link the location of the town, the article about the academy, and the two organization articles for the factions.
This would definitely make maps more useful. Some thought it needed about what is to happen with the sidebar displays or click through functions. It's also nice to have these function automatically on clicking a pin when desired. But I guess that could continue to work as it does now when there is only one article and show your mocked up selection options as soon as there are two or more options.
