I really wish when holding food* it would not be possible to hurt mobs or destroy blocks (in creative). *actually it would be really nice if only weapons could do damage and only tools could destroy blocks.

In creative feeding chickens by touch holding them invariably breaks the blocks by them - so does throwing potions - and so it's really annoying to have to rebuild what was destroyed. Taming animals it is too easy for the button to disappear as you try to tap it and you then may harm the animal.

Surely it would be much better, certainly for my 6 year son it would be, to feed/tame by just tapping/tap-holding the animal rather than trying to tap an awkwardly placed button.
