In next version the bookmark “Manage” + “Select” menus are merged. Management and selection are handled in one place, for convenience and the coming features. Also the selection moves and zooms (if too far) the map to the position (like location button).
Similar selection behavior will exist in waypoints list too.
Regarding the menu workflow suggestion, as explained here, not being so sure as could annoy all users wanting just to go to a bookmark, without doing an action.
Perhaps another idea could be to offer the context menu while being in the list, so not have to go at the map first?
