The refreshed header and navigation deliver a modern, intuitive, and efficient experience across the app shell, form pages, and view pages. This update improves visual clarity, reduces vertical space usage, and aligns with modern Microsoft 365 design patterns.

As the feature transitions to general availability (GA), the refreshed experience remains opt-in, allowing makers to control adoption and validate the experience at their own pace. Makers can switch between the classic and refreshed experience using the Header and navigation refresh app setting:

Auto (default): The new experience is off for apps, except those apps created using Plans.
Yes: Turns on the new header and navigation experience.
No: Keeps the classic header and navigation experience.

Key aspects include:

Modern app header: A simplified header layout with improved spacing and icons that align with modern Microsoft 365 design patterns and enhance brand coherence across apps.
Streamlined sitemap: A cleaner, more readable sitemap structure that helps you find what you need faster.
Condensed page headers: Form and grid page headers use less vertical space, maximizing data visibility and reducing scrolling.

The GA experience also incorporates feedback from the preview phase, including improvements to command spacing, reduced non-scrolling header footprint, and targeted visual adjustments to improve page density and usability.
