Movie covers supported?

Is this supported? For now I’ve added a single movie the the internal memory, it’s a folder with the .MKF file and also a .JPG file which is the cover of the movie.

In LeiaPlayer when I select on the left Internal Memory I see the folder but it’s just a simple gray folder. It would be nice if this could be replaced with the .JPG inside the folder.

Even better would be a presentation like this but maybe I’m asking for too much:
