Filters for the tools Map Regions and Map Counties that allow the user to filter for sizes and cache types. Similar to the D/T type / size filter for the Map D/T Matrix-tool that helps you fill the D/T-matrix with a certain size or a certain cache type but it would help you collect counties with a certain cache type or size. Trying to log Multis in as many different counties as possible in a country for example.
I know multiple people that keep private offline statistics for these kinds of things so I'm surprised I couldn't find a feature request to bump, might have been bad searching on my part. :)
