The additional information that can be selected for the images like: Clock and Date.

It would be nice to have the feature to see the current month and date like a small calendar.

Also it would be nice to see what image(s) are currently selected and shown,  in the playlist, if you would like to remove it from the Playlist.

It would also be nice to be able to click on an image in the playlist so it would be selected for the monitor at once - maybe by double clicking on the image in the playlist.
