Scheduled Production branch selection
Especially for e-commerce, it would be nice to show a tweaked version of a site during a timeframe. Prepping that work in a separate branch (visual theme changes, pulling data from a different dataset, etc) and then on a given time swap master to point to that branch and then have it switch back at another time would be amazing.
I don't care if it's in the GC UI or done through the (planned?) management API.
