Close of Build

Where can we download the "Showcase UWP App Sample" Jonathan references from 6:00 through 8:00?
Where can I download the new nav pane?
How can you make the Back button in the splitview pane have a different background color than the window close and minimize and maximize buttons?
will there be a default splitview responsive template we can use for our projects?
Sorry to burst your bubble, Microsoft, but no serious desktop user on Windows 10 cares about "universal Windows apps".
I am also looking for the Contoso Entertainment premium app sample. I was at this Build session and they said they were on the Dev center for download but I can't find it.
Hi
The WDG Design and DX dev team is working hard to complete the Media App Sample and will release it this month, likely in the next two weeks on this GitHub repo: https://github.com/Microsoft/TVhelpers

@Roger: you can design for the plain old Windows app or move up to modern design and make your app be accessible to larger user base with UWP. That's the beauty of "Universal Windows Platform".

Karen and Jonathan: Thanks for the wonderful demo. Cheers!
