Level Buttons on detached render window

[wdnv]

Hello

I'm using version 5.6. For presentations the option to show the rendering port on an stand alone window come on handy, but when you need to change the level of the design, you need to close the window, change the level and open again the detached rendering window.

I think it would be nice to have the option to change levels in the detached rendering window instead of coming back and forth from the main application.

Thanks
