This one I can answer for you. It’s by design: New "episode" at the front called "Show" - Is this intended?
As you can see from that thread - it’s an odd choice since the functionality was already there without needing the card (I just posted more about that just today). It’s weird… and likely not going away for “reasons”. Maybe once it comes to AppleTV and Android it’ll get enough push back. You do get kinda used to it but it’s always jarring to me and others.
This one I can partially answer. This is done at the account level now (in the Online Media Sources section), not the client level like it used to be (which I like because I turn them all off). I’m not sure how this works with managed accounts. It should be in the “restrictions” section but maybe it’s not there yet. Sorry I don’t have any managed accounts to check and the Plex documentation doesn’t mention it. Hopefully someone else can pipe in.
This one is just part of the New Experience but you might solve it by trying the new Plex Preview v9 which has adjusted that navigation menu. In this newer version it allows more than 3 favorites and it’s a little smoother to navigate (in my opinion). Check out this topic: Plex Roku Preview: A Faster, Simpler Navigation Experience
