Add pixels in the skin that serve as a config for the mod, then create a page that allows you to configure these pixels. This system is inspired by the ears mod. This would allow for much more customization and flexibility. Thank you for your time and mod!

This is something that could be done with a mod, Fresh Moves being a resourcepack makes these types of features impossible to implement.

Hrm. That's a bit annoying since it's kept in the skin file and could just be done with queries, or so I thought. Thanks for the answer though
