- 18 November 2014 - Custom URL's are available to link directly to some specific state of the map. For example, the URL forkinganddividing.com/#_0_00 will load the map with the ω-stable region highlighted.
Look in the address bar to the find the custom URL. They are available for large regions, small regions, theory examples, forking characterizations, etc....
