Please Restore "Slides as Background" in the next update

The latest update has "Upload Slides as Background" shaded out as an option. (In the Advanced tab). Offering that option made it a lot easier to set up my meeting room, so please restore this option in the next update. 

I don't have a problem with the new presentation mode, but why can't you offer both? "Slides as Background" is super easy to load and then you see the participants and chat super easily without having to organize it yourself. PLEASE RESTORE THIS FEATURE!
