The underlay function is a limited tool that provides inconsistent results. 80% of the submitted ideas about underlays are about providing more fine-grained controls over the visibility/graphics of an underlay. Instead of providing yet another tab or button to control V/G for underlays, how about we just link to another view? Rather than selecting a base level, users should just be given the option to link to another view. Like any other view in a project, that view will have full V/G capabilities and allow all of the fine-grained controls that users are looking for in their underlays. Then, the primary view containing the underlay can provide some controls to adjust the overall V/G of the underlay.
