Dreamweaver Application "window" on a mac

I am switching from windows to a mac and having trouble organizing multiple application "windows" on the mac. I am trying to run Dreamweaver and Photoshop on the same screen. When I use Dreamweaver under windows, i set up my workspace but the whole program is encapsulated in a bounded window. So when I run another application, I can put that in its own window and run them side by side on a large screen monitor.

However, when I run Dreamweaver on the mac, i can't see how I can "encapsulate" all of the panels and doc window inside one object so that I can move the whole "window" to one side and open another window with a different application in it.

Maybe it is different on the mac, but I am wondering how to run two application in side by side windows together so that I can see all of an application - including the doc window, the toolbars, the panels in one "object" so that I an easily see and copy and paste items from one program "window" to the other.

Any advice would be appreciated.

Thanks
Mark
