I could get very little work done if I couldn't reference something why working on something else. Often I need to reference more than one thing. I also may have a result I need to see separate from the source of that result I want to edit.

Maybe the ability to display references should be a feature in your tool?

As for my experience from Blender, you either utilize its UI to display it where you want it or put the references directly into the scene. Its also common for 2D artists to just use layers on the canvas for keeping references.
