That's the first time I've heard someone complain about the lack of a workflow breaking feature. Are you a Windows user?
Then you aren't paying attention. The support board and forums are filled with people who absolutely hate floating window designs for apps. It's a very distracting and cluttered way of looking at a palate-based app. I can see my desktop icons, or my other open apps behind my work? It's extremely distracting.
How does that break my workflow? And no, I'm not a Windows user.
That's what's great about it.
Explain.
And I'm sure some people do like it, I'd just like to see the option to turn on/off the application frame like you can do in Adobe applications.
