The resting system as a whole is not a lot better if you only use supply bags and short rests aren't more interresting or meaningfull.
(I can't even understand that some players are fine with it.
What's the next step in crpg ? Buttons to auto regain HP because its sooo coool in BG3 ?)
But at least the food supply system makes more sense and become pretty cool.
What you're doing after click 12+ is not related at all to the resting system.
So exactly the same as it worked in bg1, bg2, nw and a lot of other games. Of course, I know that doesn't mean it should be like that, but let's face it, it doesn't work differently in past games.
