I don't have your experience, (had to google HMI) but I've been looking at UI's for 40 years and know a good one from a bad one. Hubitat is a pretty tech savvy bunch so the design UI can be fairly dense IMO if its well organized. What the wife sees is up to you.
But what I'm referring to dovetails into your situation. Imagine a button somewhere on your dash that said "Design View". Clicking that would show all the edges of all the devices and the three dot menu. Another might be Zigbee Details and the Zigbee details for each repeater would show, click again and they disappear.
Just a thought at the moment.
P.S. This might be useful re your question yesterday that I can't find.
I'm going to be visiting the same topic soon.
