If you want further information, provide more details about what you are trying to accomplish.

If you want an account statement, why not issue a statement? See https://guides.manager.io/7022.

If you want to change a title, see https://guides.manager.io/7877.

If you want to move information, look at other built-in themes. I already gave you that link.

The questions you are asking suggest you don’t have programming skills yourself. If not, hire a local programmer to write a theme for you meeting your exact needs. This forum is not a coding educational site.
