The newly added register_processor option is really cool. However, even the machines are not registered, their recipes can still be shown in JEI. Which could be a bit confusing for players.
Could you add a separate config option for recipe registration of each machine, or make them depend on the availability of corresponding machines?
Thank you!

Ah yes, good point - I suppose it would best make sense to hide the recipes of the corresponding disabled machine :)

Sorted for next version!
