Suggestion: Make a different texture at the central, side side of the CraftingCore. Otherwise, you have to look for the center for his recipes(or immediately mark it with a sign so that the recipes work).
The plus of this will be that it will be easier for players to create something on CraftingCore, and the creators of modpacks will use it more often

I'm not quite sure I understand what you are requesting here.

I want to suggest making a "Red indicator" on the front texture for a simplified search for a center for crafting

I'm not sure if this is necessary. I think it's pretty intuitive the way it is now
