I’d love for Tailscale to be configurable at a basic level in the UI. Perhaps the following settings:
Tailscale login that shows the login URL and/or a QR code to scan to add your device to the tailnet
Tailscale up/down buttons to connect or disconnect
Toggling Tailscale ssh/accept dns/other Boolean settings
Choosing exit nodes (and whether local networking is available)
Perhaps other things too could be added but the first two or three would probably satisfy 95% of peoples need to ssh to configure Tailscale and let them use it without needing to ssh.
Alternatively some of those settings could be exposed using Tailscale’s web server (usually intended for NAS/media servers but would also work here) for picking exit nodes and such.
