I appreciate your help (to explain everything etc.), but actually you don’t have to convince me that your Overview screen is perfectly design for my needs. No it is not. 
The feature is not only “play next”. The feature is (as topic title shows) “go to tv show (on currently playing episode)”. This offers not only a quick “play next”, but also some more options.
After clicking a lot of times on several images, I found what you probably mean:
On RC I opened the dialog of the “currently playing video”, then I hit the 3 dots and clicked on “Go to TV show details” (I assume you mean this, when you say “show info”):
Then I came to following screen:
Here I clicked on the image, but then just the screen disappeared and I was back in the previous one (see first screenshot).
However after doing this a couple of times, I recognized, that BEHIND the “currently playing video”-dialog, the screen changed. So I “minimized” the dialog and then I came into the tv show list. YES, MY LORD, thats what I was looking for! 
However, I would have still one improvement (that prevented me from finding this “feature” 
). If you click on the image, can you minimize the “currently playing video”-dialog then automatically (to see the list directly)?
