Just exploring the new physical material in V7, the first thing I've delved into is glass.  In the legacy shader IOR was separate for reflection and refraction, meaning we could adjust the reflection strength of the glass independently of the refraction.  I'm just trying to get my head round how we achieve this now?  Is there are guide somewhere for the new shader or a thread where these questions have been asked before?

You can't achieve this now - because in the real world, the IOR for reflection and refraction is always the same and can't be different. This is one of the cases where the Legacy material let you create unrealistic materials.

The closest thing you have is adding a Clearcoat which has an independent IOR (this would be like adding a layer of lacquer or varnish in the real world, thus giving two different materials that can indeed have separate IORs)
