possibility to react to all items in player view

[juancarlosfarah]

Users should be able to react to all items in the player view. This will add interactivity and make the interface more interesting.

Other affordances, such as commenting, rating, adding to favourites, or discussing an item with a chatbot, could also be interesting additions in the player view.
