It shouldn’t matter if the user is leaning or jumping or whatever. If the variable says “is_person_standing” then the only information I get out of it is whether the person is standing or not. It would be much simpler to use enums to represent the state if there are such other options. If you don’t have enums in your language, then use constants.
I won’t be pirating manga if I can actually pay for them. Some apps exist, like mangaplus, but they pale in comparison to something like tachiyomi. And then there is webtoon which shoves an ad in my face even though I purchase content weekly to read. And webnovel is atrocious with how I have to wait 5 seconds for an ad before they show me yet another ad every time I open the app. I just use koreader now for novels. I do buy physical volumes to show some support back. But a Korean series that I am reading does not have a novel published overseas, kind of a bummer.
