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
        }
    }
}

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

Quorum doesn't return a message error clearly specifying the cause of an error (from a user standpoint) when the transaction manager fails to Quorum (e.g: 400 bad request, ...).

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?).

Describe the solution you'd like to see implemented
When adding channels to a new profile, it has been suggested to know which channels are present in another profile. My suggested solution to this is to have a drop down where the user can select which profile they'd like to display and filters / additions would be based off of that instead of the "All Channels" profile.
