Environmental reflection view mode

Hello.
I think it would be great if we could link up an environmental reflection texture to materials or if we could enter a reflection mode like in Modo. It wouldn't have to be anything fancy, just something basic. It'd help to inspect the consistency of highlights across the subdivided geometry (especially at points of high valence) a little bit better than with specularity only.

I think, this is essentially the same as MatCaps. http://voidworld.cmcproductions.co.uk/index.php/topic,1088.0.html

Well, I was thinking about something simpler, but yeah MatCaps would be great.
Thanks for pointing this out.
