Get together with the developer of the Extra Bit Manipulation Mod. And work out an integration between the two mods allowing you to add the stats and abilities of Tinkers weapons, tools and armor with the limitless aesthetic potential of Extra Bit Manipulation.
Make an option in the config file to turn off the items being visible within the smelters. It would act like the option "renderInventoryInWorld" where it doesn't show items in the individual blocks. Even combining the two would be awesome. I suggest this because the items in the smelters is causing fps drops when I look at them; especially very large smelters.
