Each theme can have its own mascot and lines. Leave a field empty to use the theme's built-in default (shown faded). Picking a tab previews that theme on this page.
Found automatically from Nginx Proxy Manager. Group them, rename them and pick icons. Icons are names from
dashboard-icons (e.g. plex, sonarr);
leave empty to use the site's own favicon. Services you haven't grouped show up under "New / other" on the dashboard.
Anything else you want health-checked: a NAS, a router, a box on another network.
Keys are stored on the server and never shown again (you'll only see "saved"). Changing an address means typing its key again, so a key can't be sent to a new server by accident. Test checks what's saved, so save first.
These protect the dashboard itself, so they can't be changed from a web page.
