@RichardPilbery Hi there - thanks for this, and sorry for the slow response. I'll get around to testing this and merging it if all looks good. Would love to know what you're building!

UI looks great! SSIDs are sorted by strength (I have two networks close by, my home network is listed first).

Why blocking the ssid's names? Even if I was your neighbor and being able to view them, I'd still need their passwords to hop on the local networks 😉

And didn't feel like stepping on any toes tonight 😉
