It’s difficult to see how much energy a recipe requires due to the lack of commas, so I think simply adding commas (and a space before the “FE” whilst you’re at it) would do wonders in making the JEI recipe screen more readable. I think the same should also be done for the machine GUI itself. Since the JEI GUI uses the machine GUI, I’m assuming it only has to be changed in the machine GUI.

Game version: 1.18.2

Good suggestion, that will be done in the next update :

(E is Tech Reborn energy, for the forge version it show "FE" of course)
The same formatting will be applied for fluid amounts.

That is wonderful! Thank you.

Fixed in update 0.7.0
