Sonarr takes care of it

On my synology nas I have installed navidrome to serve the music, and consume it via web, and a few android and linux apps like ultrasonic or supersonic

Depending on your level of paranioia. First, you don’t expose your containers, but their port(s).

With a reverse proxy, you will likely expose only 1 port, 443, no matter how many apps/containers/ports it will be pointing internally. For this, having a proper dns setup will be key, and a service like cloudflare dns (not tunnel), which additionally you can proxy your proxy. Also, you will need certificates (letsencrypt) for your traffic to be encrypted. Here, everybody will potentially have access to your services.

Another option is a zero trust tunnel, but as you had seen streaming may break tos. It will be likely enforced if you stream a lot, but I seriously doubt you’ll get any problem by having sporadic one or two users.

Tailscale, you need to add all the devices you need to access your services into the mesh, and you’ll need to re-authenticate every one again every few months.

Setting up a VPN (selfhosted) will require your devices to sign into it when accessing your services, and it seems to me the best approach as this way you will nave the most control over your setting.

Don’t forget to mention that, for this to work, your ISP should provide you with public IP, because if on CGNAT you will have to go with something like tunnels or tailscale.

Definitely a la IE

I think that would be something related to your DE. In my case, I have the Plasma Integration plugin in both Firefox and Chromium-based browsers, allowing me to play videos full screen for long periods, the only nag being that if I have it full screen on one of my displays but there is any other window focused, it triggers the screensaver. For those cases, there are a few ways on KDE to prevent the displays to enter any saving mode with no more than 2 clicks, or a shortcut if you prefer to configure those

Protonvpn has a free tier

I surely missed that setting. I am playing with it, it seems 85 is the sweet spot for me. Thanks!

Have you setup your home screen? You can do that on the dashboard, hiding, grouping, etc.

If what you’ve watched has nearly ended, it won’t show for continuing. I have the opposite issue, some shows has a long outro/preview of the next episode, so I have to either mark it as seen, or fast forward near the end for it not to show on the continuing watching section
