I am trying to pass pem-encoded client certificate to proxied service via a X-SSL-Cert header, like so:

sub.example.com {
    reverse_proxy 127.0.0.1:8000 {
        header_up X-SSL-Cert {http.request.tls.client.certificate_pem}
    }

    tls {
        client_auth {
            mode require
        }
    }
}

I like how Simplepush presents a couple of different ways to generate push messages on their website:

https://simplepush.io/#libraries

How about having a similar feature directly in the server GUI? That would include the bits documented here https://gotify.net/docs/pushmsg

A parametrized option to set the blocksize would be useful to experiment with. As quorum is used in a private setting I think this option should be available

E.g. accept missing leading 0

In osx/updater/updater.go, we're referencing an ancient Go package, which has moved to a new location. Right now, the updater doesn't build (should we test this on travis?).

Is your feature request related to a usage problem (not a bug)? Please describe.
When u press 'T' in the YT player it enables theater mode. It would be nice to have for FreeTube to also have this feature.

Describe the solution you'd like to see implemented
Press 'T' to go in/out Theater mode

Describe alternatives you've considered
