West Virginia

Six regions on county lines: Northwest WV, North Central WV, Charleston/Huntington, Central Mountains, Southern Coalfields and Eastern Panhandle.

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.
