right now when you need to create graphite you need to smelt either graphite dust, coal or charcoal in a furnace. sadly this causes the problem that you can no longer shift-click coal or charcoal into a furnace in the fuel slot. it's a minor annoyance but would it perhaps be possible to add a new way of creating graphite?

perhaps ore-dictionairy graphite dust with coal/charcoal dust or perhaps change the cyanite reprocessor to also function as a machine to generate graphite instead of just cyanite, giving more use to the machine.

This can be controlled via config settings already. For your case, you want to set registerCoalForSmelting & registerCharcoalForSmelting to false, and registerGraphiteCoalCraftingRecipes & registerGraphiteCharcoalCraftingRecipes to true.

This will prevent you from being able to smelt coal/charcoal (and thus eliminate the shift-click problem). Instead, you will have to craft graphite bars from 2 gravel + 1 charcoal/coal.
