Is it currently possible, or would it be possible to add, the ability to assign an underlay to one of the six standard, not custom, ortho reference planes?
When I make a custom plane (similar orientation to one of the XYZ planes), and then change the view, the underlay disappears. I need to select the custom reference plane again to get it to show again. I switch between ortho and perspective views often and I need to repeatedly turn the underlay on again each time.
My desire is to be able to associate an underlay with each of the six standard XYZ planes, and that the appropriate underlay would automatically become visible for the ortho view being used.
In addition, sliders for the scale and positioning of the underlay, similar to the transparency slider, would be a welcome addition to the Reference Plane Parameters Palette. A key shortcut for global Underlay visibility would be good to have as well.
