OSMC Skin Home Movies/TV-series widget suggestion

This is how I would like the Movies/TV-series widget (home shelf) on the Home screen to be:

Priority from left to right on the screen

  1. Any unwatched movies/episodes
  2. Recent watched or random (by selection) movies/episodes.

By this, the widget would always be populated which looks a lot nicer than an empty widget (if the option “show recent…” is selected and no unwatched movies/episodes exist).

Related is that the widget header on the home screen really shouldn’t read “Recent…” since it in fact displays unwatched! Don’t think there is a need for a header at all, so it might as well be removed.

Is it possible to add custom widgets, similar to how it is described here?

It seems like you can create a widget using any string for example “plugin://plugin.video.genesis/?action=movies_added”. This would be very helpful. Is there perhaps a file I can edit to add custom widgets this way
