Many times when Portal video chatting with other people especially who are using Android or iphone smart phones, the lanscape image of theirselves displays sideways on your Portal. It would be very useful for Portal to auto rotate the image of them to be the correct way up or at least to be able to rotate it manually. This saves asking them to rotate their phone and having to view each other squashed on to portrait instead of being landscape.
NB ...Zoom does it!
