I assumed you wanted avoiding randomizing the recipes altogether - implemented an option that'll go live with the next version to not touch recipes at all and neither change ingredients, products, or the required craft time.
I don't understand what you mean with the second point? To avoid changing quantities for certain entities, you can choose "Custom" mode as "Randomization Mode" and then check all you want to randomize and leave out what you don't want randomized.
So if you want to randomize all properties except personal equipment items like armors, you choose "Custom" and then select all properties except "Randomize personal equipment".
