A couple of WiFi related questions

I have a couple of nearly but not quite finished projects and need to fiddle with the code often. Assigning an IP address in the router is not always feasible, so I tend to use the discovery service quite a lot. Is there any chance or a plan to add an mDNS service at any point so that at least for us Mac users it’s easier to find a PB in the network?

At the moment I’m also working on a battery-operated project that uses an ESP32 and a PB that communicate via the sensor board serial. Both have WiFi off, and I turn it on by long-pressing a button on each. I would really love to have to press only a button on the ESP32, then send a signal on PB to turn on WiFi as well via toggling a variable or similar. Would there ever be an option to turn on Wifi from within a pattern? I could in theory add a relay or optocoupler to PB’s button and do it in a ‘hardware’ way from the ESP32, but I’d really like to avoid that:)
