Flexible icon-based links to any map from site map pages

NetBrain currently limits map-to-map navigation on site map pages to fixed links, such as neighbor site links available only on the NBR page. Users cannot place a custom icon on any site map page that links to any other map of their choosing. This enhancement would allow users to add configurable icons to any site map page, each linking to a specific target map, providing flexible navigation across the map hierarchy. This would give customers greater control over how they traverse related maps, reducing the need for manual navigation through the map tree.
