Please take at look at my spelling and grammar annotations and feel free to fix them. Why is the screenshot labeled with red explanation boxes taken in dark mode while all other screenshots of the README are already captured in light mode? Can you fix this inconsistency?

Since the UI is always changing anyways and NC 25 gave us the dark theme as default according to the system settings, I'd just leave it as is (also because of lazyness 😸 )
