Discourse bug. I’ve spoken to @Loki about it but he apparently has bigger 
to fry. jk.
Seriously, though, I appreciate your review. And your analogy.
TP-Link dumbed-down (further) their Deco Mesh app interface recently. I run the old app on one device, the new one on another. 
later… with the introduction of several responsive features via firmware, the new Deco app is, on balance, an improvement over the old.
