Missouri

Nine regions on county lines: Kansas City area, St. Louis area, Mid-Missouri, Northwest Missouri, Northeast Missouri, West Central Missouri, Southwest Missouri, Eastern Ozarks and Bootheel.

In the editor each region takes a level with one click. When one region needs more detail, split it into its counties and set them one by one; merge it back when they agree.
