When logged into the dashboard it is easy to se all devices and a tag that shows when routes are being advertised. The only thing is that there is no display IF route advertising was left ON or OFF at a site.
IN our case I leverage this to access remote devices that cannot have tailscale installed on them for remote management. In many cases the advertised route would conflict with other sites if I left it on.
Just would be nice if there was a checkbox or a green / red color difference to the advertised routes tag if the routes were turned off or left on.
