This sounds like a fantastic mod for players who want more control over their fertilizer and lime usage in the game. Being able to adjust the levels from 10% to 200% gives players the flexibility to fine-tune their farming operations according to their needs and preferences. The fact that the adjustments are saved in the savegame folder ensures that players don't have to make the same changes every time they start a new game or reload a save.
Moreover, the compatibility of this mod with other mods that add additional spray types is a great feature for players who like to enhance their gameplay with different options. Multiplayer support for admins to adjust levels adds another layer of functionality, making it easier for server administrators to manage settings for the entire group of players.
Overall, it seems like "Adjust Spray Levels V1.0" is a valuable addition to the game, offering more customization and control to players who are looking to optimize their farming experience.
