It kinda sucks how everything happens as fast as you got aps. Picking up items, mining, gathering, repairing, sciencing and dropping items is totally not something has to be regulated with action points. If you remember, in fallout originals only combat had action points. And it was like that for a reason.
To avoid some abuses and whatnot, you would get the infinite ap peace mode by first ending combat and then regenerating all action points.
Opening and closing doors should still cost action points. Same as sneaking.
