Improved Admin Navigation and Performance

Admin navigation now moves toward a clearer tab structure. State handling improves across relationship fields, previews, and connected-system screens. The CMS reads more as one environment than as a collection of custom views.

Performance improvements

Performance work in the same period supports heavier editing sessions. Custom objects, Partner API flows, theme previews, and Website Builder blocks can keep growing without making every admin action feel slow.

Keeping the admin responsive

This is part of ongoing work to keep the editing experience responsive as Basker handles more complex sites.
