Filters for lifetime map display

Oh, and I forgot to return to my first point. This might be a separate feature request. I’d love a timeline type profile to show completion by year or some arbitrary unit. Perhaps it could be similar to the miles run graphs on Runkeeper where it’s a bar or line graph over time showing percent city completion and you can control the endpoints and bin size. If you implemented some sort of filter on the activities, then the interface could show a percent completion for the runs represented on the map with the given filters. I imagine this would be calculated as if those runs were the only runs, such that the sum of percents across two years would exceed the total city completion percent since there would be overlap.
