I often run out of spell slots in a fight for heal, like im more or less midway through the fight and my cleric becomes completely useless. Its like the enemies also gets better rolls than me nearly every fight so I end up with a downed character very often. Throwing a potion to heal them up becomes my only option. Although I dont mind reloading if the fight is completely doomed, I prefer going as far as I can in the fight before doing so.
I enjoy being able to heal characters even if I am out of spell slots. Clerics dont have other options than a long rest to restore said spell slots and if you havent found much food yet it becomes very restrictive to rest. (I rarely lack food though unless I nothing)
I think you should be able to administer a potion i.e. make someone
drink it as an action, but the throwing is just a silly nonsensical gimmick that steps on the toes of Healing Word hard.
Like I said earlier somewhere, it would be cool if mobile characters with Disengage skills like Rogues could have that extra perk of being good combat medics, running swiftly up to a downed PC to administer a potion. That's much more of a tactic than everyone including enemies just throwing potions left and right.
Downed PC's should also be more consequential than the next character just getting them right back up into the fight by quickly tossing a potion.
