TL;DR
hope the mod settings will add a collapsing function based on the mod name!
What?
Depending on the number of mods, it has more and more settings, and when you want to set a certain mod parameter, it takes a long time to look up in there to find it.Of course you may say that there is a search function, but it can only search the content of the setting, not the mod name, and if the mod is localised (e.g. Chinese), it will be even harder for you to find the setting you want in there.
Why?
Factorio, being a game with a huge number of mods, has this feature to make it easier to manage mod settings, so why wouldn't it?
