Select single source while in fullscreen

It would be nice to be able to right-click on a source while in fullscreen and be able to get a single source view. This works well in windowed mode.
Also, be able to digital zoom with selecting a part of the screen would be nice as well.
Also 2, be able to select select ‘zooming steps’ e.g. (1-10) when using middle mouse scrolling bar.
