Dialog-free Mixdown

An added feature to just mixdown, no dialog prompting.

I wanna push a button on my surface controller labeled “mixdown” where it just does it.

Obviously, the ability to get to it via a “Mixdown Settings” dialog would need to be added.

This would be similar to how Render In-Place Settings dialog works hand-in-hand with its Render counterpart.

I hope they follow through on this with Freeze, too. It would be nice to have a dialog-free Freeze.

Back to Mixdown: it should have a “silent overwrite” that actually is silent, too. Even on a fresh launch.
