I looked up some latching circuits and stuff and it was all too complicated and overengineered for my taste so i performed *big think* and came up with this incredibly simple solution that is perfect for me
Basically you press the button which opens the mosfet and allows the IC to boot and then the IC pulls one pin high and keeps the mosfet open and you can let go of the button. This is very fast so you can just barely tap the button and it will work.
And then when the IC wants to turn it self off it just pulls the pin low and boom, mosfet closes and near zero energy gets wasted. disgustingly simple
