If you wish to swap blacklists just simply COPY itemBlacklist.cfg from one of the folders. COPY DO NOT MOVE THEM!!
Condensed Chisel just makes it so that it only shows one of each chisel block, clicking these blocks show all of the varients

Normal will make it so you see all of the chisel blocks (leading to about 15 more pages of blocks)

Just wanted to make this an option if you get sick of one just swap it!
