Hi Jono,Yes, it has been discussed on the mailing list already. People really like the idea. :)Actually, the person who made that mockup (David I believe) made several. I personally much prefer this one: http://unity.exemo.net/3/No flipping action, just a graceful slide-in. It feels much more natural to me that way, also because it's a less jarring change (the only animation involved is sliding-in).
