[REQUEST] World Viewer

[Rudometkin]

Are there any mods that pre-generate a portion of a world and display it in a map, so you can see your world generation settings put into practice from a map point of view? I'm doing a lot of testing, and it's difficult to figure out when I've found a good ratio between oceans and continents. The only way I can see my worlds is by flying around and loading it myself, which is very slow. It seems like there aren't any of these mods out there, but I don't want to spend all of my time searching if someone here already knows of one. Thanks.
