Can you add please a setting for fourth level of quality modules?

I mean Tier 4. But it's not vanilla, so I need to check the module name of other mod - either "Tier 4 Modules" or the T4 modules of Secretas/Frozeta. I use last one, so they have other names of their modules.

After changing the files of your mod, it works:

Add following lines:

- data-updates.lua:

data.raw.module['quality-module-4-S'].effect = {
    --original value = 0.3
    quality = settings.startup['quality-4-effect-tweak'].value
    }

- settings.lua:

    {
    type          = "double-setting",
    name          = "quality-4-effect-tweak",
    default_value = 0.3,
    setting_type  = "startup",
    },

- locale/en/locale.cfg:

quality-4-effect-tweak=Quality Module 4 quality multiplier

quality-4-effect-tweak=Vanilla: 0.3
