I agree. I know it's easy to ask for things that will cost someone else but I'd like it too. In fact, something akin to the graphs for a stock that google finance has would be awesome. They have checkbox for other stocks, each when it's on their shows up in a different color.
For Mapillary it could be some others you have connections with to easily see where you overlap. And instead of the stock indices, those check boxes could be for everything within the last year, top uploaders or whatever else makes sense.
