We designed Foneo to have a very simple but yet useful interface. We have 2 display modes - video layout and screen sharing layout.
a. In the video layout, we have optimized it for video viewing and desktop viewing. To go full-screen, double click on the screen.
b. In the screen sharing layout, we automatically switch to full-screen to optimize the document or presentation view. To exit full-screen, double click or hit Esc.
