I've been keeping my eye on this mod for a long time as a last resort for my modpack, as the configuration options are quite minimal for the chunk loader. I really love this mod and all the different rails that offer so much more than just simple tiered rails with slightly faster speeds.

That being said; The only thing that I believe needs any significant improvement is not the chunk loader itself but just being able to customize how the chunk loader works. I have several things I would love to see as options or at least something in the config that would allow more customization for it:

• The ability to change how much time each item can increase the chunk loader
• The ability to change what items are available to add time to the chunk loader
  • you could do it however you like, but example {["minecraft:emerald":10,"minecraft:nether_quartz":30, ETC]} This would actually make it super easy to just add and remove whatever we wanted to use as chunk loading "fuel items"
• Designate what, or if, items get dropped when the chunk loader breaks
• The ability to adapt the time requirements to the amount of chunks loaded (if 1 chunk, its only one minute BUT if 3x3 chunks would be 9x minutes)
• The ability to choose if you want online or offline (or both) chunk loading only
• Lastly, I think you should separate out the chunk loader block into its own mod, people would go nuts for a proper chunk loader that can do all this and actually does "fuel into time" system right, like the one you made

Please let me know whats possible and whats not, I would be happy to explain anything that isn't clear
