Uhm... Huh?

Only staged commits get committed. Some programs​ automatically stage all changes and then commit them.

So, you can have a lot of changes. If you stage 2 of them and do a commit, only the staged get committed. So you won't break everything but keep commit small and more manageable.

No?

Well yes, I get that 😂 but when you click yes it actually means "just this once" 😂
