I think it would have been better if the BBC had arranged for one studio to be relit in appropriate colour and with appropriate images and stuck to it for the duration rather than flitting between loads of different locations.

Based on how multi purpose it is, and how these plans have been years in the planning, that should probably have been studio E. Studio B could have been parked for the moment, and the World hours such as the current one with Christian Fraser could have been in E as well.

I agree that this would have been a better approach - although do you mean Studio C (the World News one with the screen - E is the one in the newsroom)? 

It was mentioned earlier that the BBC might have been deliberately avoiding bespoke studio graphics and lighting, but I personally think it's worked well for the likes of Good Morning Britain and Talk TV.
