There is HP, SP & TEMP healing.
I did think mainly of the kinetic damage types but there are also some less commonly used ones (magic [not force], positive, negative, any alignment).
And then potentially also custom damage types. I was thinking along the lines of the languages or currency lists where you could add entries (obviously support for these damage types would have be handled via an extension).
I feel like if you're adding customisation options might as well go all the way and allow for the most possible options. I'm not sure how the system works currently but I personally don't see a reason to omit any damage types from being able to be change, it's a great feature and if a user doesn't want to use it for kinetic damage types for example they can still just input the normal dice and ofc it is subjective just like all the others. When it comes to the presets shipped with the ruleset you can still just set them as the default dice and users can decide themselves whether to change it or not.
