Max quantity button at shop

[sand ice]

Every day, I go to every shop to buy certain items entire stock. Some are required for stamp upgrades, some are for forge, some are upgrade stones etc. It takes approx 10 seconds of holding the + button to reach max quantity and sometimes you have to do that multiple times if your inventory cannot hold all the stock. I think it would be a pretty nifty (and probably easy) QoL update to add a small max quantity button next to the + button that automatically sets the quantity to max, so you can save on the time needed for the quantity to ramp up to max.

Press max then the plus

at the bottom of the store press the quick butto, then hit the + button of something you want to buy, this will max the quantity and you just need to click on the item itself to buy max amount of it
