I use teamviewer regularly for to converse and share screen for presentations. (Similar as you would do with Skype).
It is painful to see the face autotracking constantly moving and cutting off the background....PLEASE make the default the normal video feed.
ALSO
When Presenting...why doesn't teamviewer automatically adjust the shared screen feed to fill recipients screen. This occurs when the presenters screen resolution is less than the recipients resolution. In some cases there is such a disparity between the two that nothing can be seen. There is no button to fill the recipients screen. Do not confuse this with the remote connection screen which is not the same thing and which I know has the full screen button....which should also be changed to default...PLEASE teamviewer, FIX these SMALL issues for a better experience!
Thank you!
