And for example number of professional cigar makers at the city. Grey button means not displayed, hit again and it shows total in or outside city. Hit again and it shows only inside city. Hit again and it shows only inside of city not idle and again only ones inside city idle. I know a bit complex but maybe not that bad to code. As to how to alter the icon each click. I don't know. Maybe I II III or IV in each image. Just a thought.
The idea here is to make switching view of stats as fast as possible.
