## Primary Purpose
The top navigation bar provides access to global actions and control and user profile specific settings.
Switch between locations you have access to. The selected location controls which data and orders you see elsewhere in the Admin views.

## Related Concepts
Here are a few key concepts of TWICE Commerce that relate to the top navigation.
* The top navigation maintains consistent access to key functions regardless of where you are in the platform.
* A location (or multiple locations) is always selected in the top navigation, setting the context for all data and actions available throughout the Admin.
Every user can define a range of personal preferences in TWICE Commerce. These include settings such as your interface language, personal information, and how data is displayed for you.
For example, you can save custom views of data tables (filters, columns, sorts) to your own account — those saved views are only visible to you, and do not appear for your colleagues. Only table views marked as Global are shared with the whole team, ensuring you can personalize your Admin experience without affecting others.
## Visibility and Permissions
Access to top navigation features is controlled by your user role. Your user role determines both
visibility and
permissions for
manage,
edit, and
view access levels.
