Refractive material viewport representation

[gagui]

Hello.
Is there any way to visualize a refractive or transparent material as trasparent in the viewport.
I'm just trying to do it with a V-Ray Material Builder but the objects with that material are visulized opaque in the viewport. If I do it with a principal shader it worls as expected.

Other material effects like opacity or self-Illumination seem to be missing in the viewport aswell.

Talking about shader and texture representation on the viewport, something like this: https://vimeo.com/341562345 would be pretty useful for everybody.
