I personally do not recommend using React or any hopper plugins. Hopper plugins are very likely to disable my optimizations to hoppers ,and React hooks into the internals so much that simply using it adds a bit of lag itself. React is only a positive if it can accurately identify lag sources enough to mitigate them to negate the cost it has to hook in and analyze everything (that type of code isn't "free" in cost to performance). you don't need plugins, you need to establish POLICY. disallow players to build extreme hopper contraptions.
