Improve video feedback

The video feedback is just a small square and its way to small according to me.
After looking around and contacting the support there is no way to increase the size of the video feedback.

On your Instagram you are showing that it has been possible(?) to get video feedback in fullscreen: https://www.instagram.com/p/BwpSb4CokCL/?igshid=YmMyMTA2M2Y=

Also this video at 1:13 shows big video feedback

(This is exactly what I want, but also be able to replace the metrics next to the video)

Doing this would enable it for Apple users to record the whole screen to get full set recorded and not only isolated movement.
So my other request or suggestion is to add a button that starts recording the screen (not the camera)

Another strategy could be to bring up the video feedback in fullscreen and then allow users to add overlays to the screen. This would also be very useful for recording the sets.
The second post in this link:

Shows a fullscreen recording that allows users to add metrics as a overlay.

So my question is:
Can you please make it possible to increase the video feedback box to full heigh or 50% of the screen
And, can you please add a record button that records the screen (this will include the video feedback).
