I suggest feature to add a button that will allow us to disable/enable any upgrade that we bought on the farm supply screen. The button can be placed instead of the non-functional "unlocked" button for each perk. Functionally it could work just like if you haven't bought the perk.
There's multiple reason for why, I think, it would be a good idea:
Sometimes people buy perks that they don't like and have no way to disable them except via support.
Disabling do-all cooking upgrades can be useful for more efficient use of fish and chips because sometimes you lose xp by habitually clicking all actions instead of just seasoning. It also helps with other cooking strategies, like increasing cooking time for more effiicent resource use. A way to disable them will allow players to make more flexible strategies.
Disabling potentially "hurful" perks like pet o matic and raptor refresher that you can accidentally activate/forget to disable via settings. The disabling toggle will give another, clearer, way to turn them off.

I meant the pet whistle, not pet o matic.
Sometimes I see players in chat accidentally collecting items with it with using crunchy omelette :P
