Customize lets you personalize your app's navigation by choosing which sections appear in the tab bar and which live in the More menu.
Home is permanently pinned (shown with a lock icon) and can't be moved. The remaining items are grouped into "In Tab Bar" and "More Menu." Just long-press and drag to reorder them whatever you place at the top gets a tab bar slot, while the rest stay in the More menu. The layout updates based on your priority, so you decide which sections are most accessible.
