I'm mostly stating that the descriptions of your mod settings don't tell clearly what they do. It's a string of text you would likely see in code somewhere, not a description of what changing the setting does. From your response it sounds like it modifies how the Vulcanus biomes generate, including frequency and size, but I had to come to the mod discussion to find that out instead of looking at it in the game settings.
Some mods have additional 'pop-up' text that appears when you hover over their mod settings with an even more descriptive text describing what the setting does. I think here changing the setting names would be sufficient, but you do it how you choose.
