Feature request:
How about a button that picks 4 random channels (from all available channels, and/or from the current Collection) for immediate Multiview display? That coukd be a fun new way to "channel surf" and also discover new channels in the sea of FAST content out there.
"Mutiview Roulette" has a nice ring to it too. 
How about a simple admin page in the webUI, that we could pull up on our phones to manage multiview layouts, to push with a click to the TV? To line up the 4 channels, to change what's playing in each quadrant, live. Like a video DJ.
A "randomize" button would do well here.
Or how about a Multiview API so we can build something like this on our own?
Yes please
