So when someone wants to add an option to manipulate the hist output it'd very easy to miss to update all of them in sync. And things getting worse as more options/features are added continuously. So I'd like to refactor them using hpp formats and move common code to ui/hist.c in order to make it easy to maintain and to add new features.
