Fullscreen VIEWER, not slideshow.

C1 needs a full screen preview mode so users can see what their photo looks like without all of the UI controls interfering with the preview. It makes a HUGE difference to not have useless crap drawing your attention away from the image. Fullscreen, black background, NOT A SLIDESHOW.

The slideshow feature is the only way to get a fullscreen view of an image, and this is just ridiculous that C1 hasn't recognized and acknowledged the need for a fullscreen viewer. Lightroom has had this feature for 10 years. It is necessary. I don't want the "F" key to make the UI fullscreen. I want it to show a fullscreen preview, like Lightroom. The UI fullscreen mode can be assigned to Shift F or Ctrl Shift F instead. Nobody needs to alternate between normal and fullscreen UI that frequently. But users need to alternate between fullscreen Viewer and normal viewer quite frequently. This is just common sense.
