It would be nice if we can add settings from another file, as there are old files and new ones,
I’d like to replace the settings as a whole, and not like compare every single checkbox 
or can we today?
You can select one of the predefined presets to set everything at once, but that’s it I think. Can add import from file eventually.
once you have something working you could save that file and use it as a starting point. I guess not the easiest or best thing but could give you a much better starting point.
