i have a request/suggestion to make about the material preview.
Can you PLEASE make custom previews for materials. When you double click on a material slot, the window that will pop up will be the same one that is in stand alone material preview.
I usualy spend a LOT of time perfecting my materials because i think they are responsable for a realistic scene.
I have an example of how it can look.

And maybe in the future we can even have a few different light setups to choose from and even use our own object.
Who is with me on this one ?
Thanks.
