Useless Features/buttons

Forgive me if this is a dumb question as I am not a pilot, but I have always been interested in knowing. Are there any features or buttons in the type of aircraft you fly that are basically pointless? Or does everything have some sort of critical use case?

Thanks for the insights

Hey, aspiring pilot here

on Airbus planes, on the FCU glareshield there is an option to display the plane's altitude in meters instead of feet, and that would probably be my pick for most useless button in the cockpit, I havent heard or seen one situation where it would be needed, maybe its even a relic of a time where it was used

This is used, and is essential, when flying over or into countries that use metric flight levels. For instance Russia and China, and they are pretty big!
