Another improvement suggestion just for the sake of consistency:
In full screen mode for movies, when you just select a movie for viewing, a nice pop-up appears giving some details and a Play button. For albums, the behavior is different, there the full screen mode is closed and list of tracks is shown. The detail pop-up can only be reached by a long touch and manual selection. I would appreciate, if it would become the default for albums, too.

Well, now it becomes difficult. Either we violate consistency between non-fullscreen and fullscreen for music (option A) or we have inconsistency between movie and music fullscreen behavior (option B). Problem is that when you select an album you do not immediately get to the info screen but to a detail view (which e.g. lists all tracks of an album). When you select an artist you also do not get to the artist info, but you receive a list of all albums of this artist. I can change the behavior for fullscreen to directly jump to the info screen for an album or an artist. But then you cannot use the same flow as it is possible in non-fullscreen. I admit this looks quite nice though.

Wow!
Exactly the way I would like to see it. Thanks for giving it at least a try!
But you are right with respect to the other (in my opinion minor) inconsistency this would introduce. Since nevertheless a long press would still allow the user to select individual tracks if required, I would say this is acceptable...
Honestly I never understood why Kodi treats music and movies so often so different.
