As the most of you might know, CF is a very usefull way of closing stuff up and saving yourself from lava or creepers.
But if you want to build with it it really isn't a usefull material to use. So what I propose is that when you place scaffolds, right click them with the CF Sprayer, they get replaced with CF, so this way you'll be able to create walls without having those anoying extra blocks of CF sticking out
