Menus depend on the account
Guests see sign-in. Class members have Homework; teachers have Teaching and Presentation. Administrative sections are for administrators and are not needed for ordinary study. The connection control at the bottom of the menu reports robot status, not sign-in status.

Language and appearance
Open Profile → Settings and select Language or Theme. Lab interface languages and documentation languages may differ. If a screenshot uses another language, follow the corresponding control name in the instructions.
