Having foam cover cables was a wonderful addition. But it would be nice for a few tweaks to make a creeper proof life a little less of a headache to achieve.
So I suggest 2 things
Have CF cables have an alt texture. Just like a bar running down, or a symbol to signify it as carrying power.
Have Cables be treated somewhat like scaffolding. When building a wind tower, I used foam over a wire and had to make a mold to keep the foam contained. I was wondering if it would be possible for foam to register and fill only cables instead of a giant puffball killing anyone in the vicinity when used in tight spots. Or throwing me violently off my scaffolding tower used to make the mold and crashing into the ground in a shower of tools and wires. Merging it with scaffolding would work too, but unfortunately would make it harder to use.
