The whole idea is to make this as easy to run on an Umbrel as possible. Messing around editing .env files is a major point of friction for most non-technical folks. A GUI for configuring the .env files goes a long way to making running a personal relay more approachable. Making it a one-click install from an Umbrel community app store goes even farther. Then the relay can be exposed via Tor, Tailscale, or a reverse proxy, depending on the individual's preference.
