Good advice. Sure.
But my perspective is more: make this kind of software easy to use for everyone. UX is key. I would like to see less language in apps that confuses endusers. Even if a developer might know immediately what is meant …if a user doesn‘t understand they usually dismiss the app. They most likely don‘t want to google or ask support.
