It would be really good to have an option to create slides in portrait mode. The students we work with nearly all have mobile phones, but very few of them have any other devices, so we'd like to optimise our materials for that format. When you view landscape slides on a mobile phone screen it only occupies about a third of the screen space, and rotating the phone to horizontal doesn't really improve things as the header and footer navigation bars get in the way so the picture is no bigger. I think nearpod has tremendous potential for working with groups with limited access to technology, and it would be great to maximise this potential!
