I tweaked the labels when I was working on the combined mode, where I figured they make more sense as indicative of the general, combined alphabetical area. I hadn't considered they'd be confusing in the 3-hand mode. I've split the positioning of them between the two now. Appreciate the feedback!
It does make it _less_ accursèd now, which I feel could be either an improvement or a regression. I leave it to weigh on your consciences.
I've been working on an MQTT Broker/Topic tree explorer. It's intended to help someone understand what kinds of data are moving through their broker, what the busiest data is, and just generally be pretty. https://ryanbateman.github.io/mqtt_vis/
