SegmentSelect Pane is an extension for the block editor that adds a navigation sidebar, aimed at site builders and developers handling complex page layouts. It offers a persistent interface for selecting and modifying content elements while keeping focus on the main editing area.

• Persistent Sidebar Access: Maintain constant visibility of block navigation to switch between sections instantly.
• Nested Element Selection: Access deep-level containers and child blocks that are hard to click on the main canvas.
• Visual Hierarchy View: See a clear list of all page components to understand layout structure at a glance.
• Workflow Acceleration: Save time by centralizing block selection in one pane, minimizing scrolling and searching for settings.

This tool is especially beneficial for developers and designers working on long-form pages or detailed landing page designs where precise control over block placement is essential.
