Very smooth, few ideas

No enhanced contrast or inverse video, which some users might Iike.

Really like the overview box, very clever!

Image gets clearer when u freeze the image which is nice

Id like to tap to set focus point. Better would be to give focus priority to part of image Im viewing, vs now it might focus on presenter, vs whiteboard which Im not even looking at. This means whiteboard text is out of focus even though thats what Im trying to read because presenters head is in I zoomed overall frame and I think that confuses the cameras autofocus. The AF "region of interest" should be bounded by the zoomed in portion of the screen - I think this would fix it

Icons are nice, but might add option for bolder buttons for low vision users.
