View Media Info 4 & Movie Sync between different locations

Hi,

Situation: I have a NAS (QNAP) where I store my movies & music. I have a MINIX NEO U1 media player, connected to my local network and my TV. Kodi is installed on the media player.
I have also a desktop with Kodi installed. And I also have a laptop with Kodi (when I am elsewhere for streaming, but this is another story that I still have to discover)
I would like to have 2 following features:

1. When I open a list of movies, I use as view: “Media Info”. I would like to enhance this view with following options:
– Extra info above the short contents: Writer & Runtime
– 2 buttons on the bottom: Cast & Trailer (when using Kodi on the media player, it is not handy to use the pop-up menu to go to ‘Movie Information’ to be able to watch a trailer)

2. Second feature: when I watched a movie using my desktop, then I would like to see on my TV (using Kodi on the media player) that this movie is marked as watched.
