Plans and recent fixes are on the roadmap.

Mods can ship native extensions that Crux loads into the game: hooks, in-game settings pages and state that follows your save slot. The Extension SDK guide shows how to write one in Rust with the open-source workshop-ext-sdk (MIT or Apache-2.0) and package it with CrystalWorkshop.
