For the creation of the slideshow being able to set the start and finish point to the pan of each room. Very frustrating not being able to control where the camera turns and what it looks at between stops.
Allow the user to set the start point (capture photo) then set the pan to right or left. This way you can predict where the composition will fall. This is more towards a video concept than photography. Composition of movement would be some much better if you can control the outcome. Most times the pan goes in the wrong direction towards a wall or away from the better composition. It would be a more professional feature is controls were added.
