That looks great.
How are you driving your touchscreens?
I’ve got a couple of “now playing” devices - RoPieeee and the 7" touch screen in one case, a small monitor with an Apple TV in another. I’ve been playing with the idea of building one around this new Web Controller extension: Roon Extension: Roon Web Controller v1.2.0 - #468 by nihil
I think I could drive a touchscreen with a Raspberry Pi running the built-in Chromium browser on Raspberry OS. In “kiosk” mode, the browser is full screen. Are you doing something similar to this?
I do wish it was easier to get one of these to work with a layout that’s readable from 10 feet. As it stands, the fonts are too small to be easily read.
