Feature: mDNS service discovery

In mDNS (Multicast DNS) can not only the hostname be multicasted but also service (like SSH) be multicasted.

If Kitty had a mDNS service discovery window feature, then would SSH servers pop up without knowing their hostname or IP.

I don't know if this is a big change but I see it as a benefit for new users of Kitty.

Just a thought.
