It seems like you change layout just because you can

1. Putting workspaces in a drop down box is less efficient. It was much easier to switch back and forth among workspaces by just clicking on the tabs. It is more clicks now and slower to use the drop down box.

2.The captions worspace is really hardly usable. It used to be when I was in the captions workspace, I could click on the caption text in the text area, and I could see how it would appear in the program monitor. Now the program monitor isn't even visible while in captions mode..
