Change design of detail view

how to change the design/layout of the detail view. I want to add a new tab in a detail view. I’m sharing screenshot where I want to add a new tab


You can add and remove fields and tabs from studio. You must be an admin to access studio.
Admin->studio, Select your module from the List, then You will have Layout option.
rest of things are self explainable.
