Hey Felix, thanks for your feedback, we've been considering adding the ability to optimize for a full screen on a monitor and use SL4's ability to keep something full screen but switch apps. Would that solve your issue?

ah, you mean I'll be able to play the video fullscreen in the background and switch to my browser/ide windows to the front ?

that will work I think, but I still believe that  the browser/ide windows will work better when maximized, and the video window can be a smaller but topmost window in the front, that will be better.

 

but the fullscreen mode can be implemented as a 'in the browser' app, and topmost windows requires OOB, maybe thats an overkill.
