So I'm sure like 9999999999999999999999999999999999999999999999999999999999999999999999999+ people want a nether dimension mod, right? Now I'm not good at coding or anything so I don't have any idea if this will work but what if you created a folder labeled "Nether" in each world of your worlds, and this folder contained its own level.dat (an incomplete one without inventory so you could keep your inventory that you had on Earth?), entities.dat, etc., all of which would resemble ones from the Oether mod, but there would be no trees, flowers, so on. These "Nether" folders would be accesible only when the player taps on glowing obsidian, and then appear in these worlds. The only con I can see in this plan is that each world (unless there was a way to make the Nether World smaller) would take up double the storage of a normal world. As I said, I have no idea if this will work, what do you think?
i never use that mod because i really don't know how to use that..... breeew,,,,
