I know its not a new request but being able to choose to capture desktop or even both sources without installing 3rd party software is a really important feature to make vmixcall a usable tool. Just like google hangouts and other similar apps , when hosting a remote call most of the time the person who joins has something to show... (conference kind of streamings)

Ifb dedicated channel would also be nice but for now sending some a or B bus can help.
Thank you.
