When changing the animation delay for switching between scenes from the default 2 seconds to something more reasonable where you don’t have to wait for such a long time, decimal comma isn’t supported. Despite decimal comma being my OS setting and being used for for length inputs, I have to write an American dot/point to enter fractions in this field.
This inconsistency is quite annoying, and not everyone knows USA uses a dot as decimal separator which could potentially make it impossible for some people to enter fractions.
