What?? Now I can't stretch app across two screens??!!

Bloody hell.... is this true? I was able to have my audio apps stretched across both my monitors. Now with mavericks I can't.

What's the point then? What's the advantage of whatever the heck some newfangled 'multiple monitor' support doohickey that's supposed to happen with mavericks? All I see is now is that both monitors contain the menu and dock.... whoopdeedoo. How the heck does that help me when I can't even extend the width of my applications. Grrrrrrrrrr

Uncheck "Displays have separate Spaces" in Mission Control pref pane.

Note that you will only have menu bar and Dock in your primary monitor as a result, and Full Screen will only use one monitor, as in 10.8.

I believe you can revert to the old behavior. I'm not exactly sure how, but this looks promising: System Preferences:Mission Control: Uncheck displays have separate spaces.
