I was wondering if it would be possible to allow customization of the generated waystone-names.

If I read the code correctly, the current name-generation basically workes like this: it tries to use one of the "special" names and if those have been used it generates a name using the random-name generator.

It would be nice if the list of "special" names was configurable (by biome?) and if the built-in special names could be turned off entirely.

What would you like to use the special names for? I'm considering completely removing them.

I'm currently building a little "Vanilla++" pack and thought it would be nice to add a bunch of names to the waystones.

Its nothing I really need - just thought it would be fun. If you want to remove the names its OK, too :)

The latest version adds a "Custom Names" config option which it will pick from before starting to generate random ones.
