Please Make a double Caves mod
Do you mean twice as many as 1.6, or twice as many as 1.7? If the latter, the old cave generation mod is pretty much double the 1.7 generation. Also, there's two ways to change the number of caves; the size of a single cave system and the probability of generating per chunk, which produce different results (one makes them bigger with the same separation but the other makes them closer together.
I myself prefer bigger cave systems that are more separated, but I also made it so there's a limit on how dense they can get; that requires more than a few bytecode edits though, as I did for my game, including modifying the actual algorithm that generates caves, as well as ravines.
