Hey there,
I just bought WiFi Guard and it's perfect!
I don't know if it means much (could be a MacOS thing), but WiFi Guard doesn't show some hostnames on MacOS. It does it only for some devices (3 out of 14). I'm an embedded engineer so I rely on my local microcontroller hostname to differentiate it from others.
I've used WiFi Guard on Windows for years now and I was always able to see the hostname. Anyways, it's not a deal breaker since I can set names inside WiFi Guard but meybe it could be improved
All the best, cheers!
