Currently only Booleans and List<String>s have GUI widgets created for them, so new config options using different types like Integers will be missing from the config screen,

Oh shit, it has to be made scrollable as well for any more settings to be added. It seems like the only option is to implement the whole thing as a scrollable list, then.

Yup, shouldn't be too hard of a change though.
Will also have to redo the GUI widgets for the booleans and lists to use a class instead of a function at some point

Yeah I saw the Todo's and promptly ignored them. I had a look at how modmenu did their scrollable widgets and just thought nope, not today...

We switched to YACL, this is no longer relevant.
