When textures are present/applied to the model(s), functionally in Stager really slows down. There should be alternative view ports--like Blender. 3 features--such as "Base Mode" (Hides Textures/Material Settings), "Texture Mode" (Enables Textures), and "Render" Mode.
At the moment, Stager feels very "heavy" and I think this would be a great solution. FYI: I work in an assortment of 3D applications and Stager is drastiically slower, which stinks because I would like to use it more often.
