BurnBabyBurn makes baby zombies burn during the daytime (like in new MC versions), FastFurnace is just FastWorkbench for the furnace, and Reach Fix fixes problems with the reach attribute.

Also noticed that it doesn't detect Old Combat Mechanics upon loading.

FastFurnace functionality is included in CensoredASM which is widely used in modpacks and Reach Fix is still actively maintained and thus won‘t be included for now.
