As a keen photographer, who carefully composes a shot, I would like the option to turn off the Ken Burns effect in the Android TV App slideshows, and just have the dissolve between shots. Also, I often change the aspect ratio in compositions: most are 3:2, but some slides may be square, 4:3, portrait or panoramic, so I would like them letterboxed or black barred as appropriate, rather than zoomed to fill the screen.
