Two things could quickly turn this into a QoL instead of incredible nuisance:
1) If clicking away from the menus (as if to move the character) would close the quantity box? That’d be great. We’ve seen it’s possible in other menu options that have been made like this. It’s frustrating that it’ll sit there forever unless it is closed.
2) The way it forces you to input numbers is often messing up the option we are typing in. Does it always have to have a number in there? When I type “50” what I have to do is type a 5 in front of the 1, then delete so that the 1 is gone, then type a 0. Really basic combinations sometimes take a bunch of Snuggle a Bugbear around to get it to come up, where you’d usually just highlight, type your number to replace it, instead there are wacky outcomes as it tries to limit you to 100 objects.
