Ok I'm just getting back from my travels (side-note MrMC with Plex and setting the transcoding to really low in a hotel works real well) and back to the Apple TV I do most testing with. Here's a few other notes:
Jerky playback - Went to play a recent episode of The Strain and the playback was jerky, and the audio would go in and out. This isn't the first one like this, but on the Shield it plays just fine. Here's the pastebin:
https://pastebin.com/XuYV3GXu. I sent an email with a link to the file in question.
Music skin improvement - I only have one music library in Plex, and it's the only music library set up, but when I click on Music it goes to the Service selection screen, then I need to click the Plex Library, and then I'm in music.
Music skin improvement - Same wall view as TV Shows/Movies.
Music skin improvement - Option in settings for the Music Library to default to Album view instead of Artist view. I know I can go <back on the main screen to get to the album view, but I only ever use the album view so setting the main link to that instead of Artist would be nice.
TV Show/Movie skin improvement - Right now the <back area only has 'Recently added, In progress, Genres, etc'. I would like to request that the 'Title' link be replaced by 'Unwatched'. The Title is the main click, so having it back there seems redundant to me, and out of all of those links I wouldn't use any of them, but I would use Unwatched non-stop so I don't have to continually toggle back and forth it in each of the main title sections.
TV Show skin improvement - My main view uses the wall, and then when I go into a show, the episodes are back in the list view. The list view is lacking the 'Air date - Running Time - Rating' underneath the icon. This is there in Amber and some of the MrMC Views.
TV Show/Movies Wall View improvement - There's a lot of wasted space. Remove the name under each of the posters and over it over to the side above 'Genre:'. It's already there on the poster, so it's 100% redundant. This way you should be able to get 3 rows on the main screen.
Not related to TestFlight With Emby there's an option to just show a particular server and not all of them. This would be nice for Plex since I have my home Plex server for home use and my VPS Plex server attached to Google Drive to not at home use. This way when I'm at the house it would only be one server and everything would just fill right in where it's supposed to be (i.e. Movies to Movies, TV Shows to TV Shows, and Music to Music)
