I don't think I'm familiar with Tomi's proposal. I must have missed that one?
I'm sure it would be brilliant though.
Even out of the box, if the objects (including the periscope view itself) are moveable - and evidence
seems to suggest this
may be the case - then even something like what Adriatico mocked up
here (beside the default screen for comparison) would be (IMHO) a vast improvement. It's just a rearrangement of the existing objects, perhaps in much the same way that we will be able to do ourselves "live", but one is left with no uncertainty as to what the focus of the screen is.
