I've added this mod to my pack a while ago, and I have an issue with how the items are displayed in JEI.
When scrolling through the pages, the whole game gets enormous frame drops and lags out. It's a real pain to get past the chisels and bits items when looking through the entire stock. I assume you're rendering whole blocks in the JEI window hence the frame drops? Can they be pre-loaded and pooled instead to that it doesn't lag as horribly?

If you need my full mod list, let me know.

I am sorry, but all things you suggest are already implemented.
Some versions already have a toggle to filter them when JEI is loaded, but most modern versions don't. I still need to reimplement it.
