Would love the ability to be able to as an admin, create a furnace that burns forever to have in places such as a town center. Having it permissions based would be great as im not too sure everyone being able to spawn/make them. I'd imagine you would just need to "fool" the furnace into thinking it continually had lava buckets placed into it? Im not too sure on this kind of thing, just my two cents on the development. If anyone would be keen to take this on, it would be much appreciated
Working on something very much like this. It may not have everything you want in the first iteration, but I'm open to feature requests, etc. Keep your eyes open for a plugin called DwarfForge.
