Yes, I know that, but how can I continue with movies and series that have a hub?

You can not and there will not be a update for that. That would take a lot of work.

Okay unfortunately, but nothing to do

Sure you can do something about it.. it might not a fully functional widget but it will do your puposes.

1. Install the Super Favourites Addon By installing first the jmoore repo ---> link is here
   
2. Configure it by adding a new folder which you can name whatever you like e.g "My Media"
   
3. Now add all the media ( Movie  / TV Show  /Rick & Morty / whatever ) to this folder from within kodi by using the context button and add to superfavourites dialog
   
4. In the skin settings & widgets  add a new widget and Link it to this "MyMedia"folder that you have poulated 
   
5. Voila : all mixed media wdiget ... but it will not be pretty like native with icons & bells & whistles....but at least you will have it on your home screen !
