Is there a way to edit the layers in a superflat world? I could see that you can 'remove layers', but its kind of funny that you can't add layers, when it says 'superflat customization'. I was looking forward to making some redstone stuff in Creative mode in a superflat world, and I needed a world which was at least 15 blocks deep, but not so deep that I can't build something high. None of the available presets match my requirements.
If you look at the presets list, on at the top of the page it has a box with things like: 2:7,2x3,2:1.
This is referring to the block id of the layer, and how many layers of that block, by playing around with that, you can get the world that you want.
If you want to describe the world that you want, with what blocks and how many layers of each, I'll make the code that you have to put in there and post it here for you, so that you just need to put the code in the box and press ok.

If you look at the codes for terrain presets you can easily change the heights of layers
