I've had some fun conversations failing to explain why someone needed to try a multi monitor setup. It seems one could just get used to small screen. I normally use a redmagic phone. Today I had to test a website on an older iphone and got some claustrophobia vibes from it. No idea how I've ever used it.

I did some experiments with this https://synesthesia.go-here.nl but was to lazy to sufficiently learn it. I never got around to writing a code viewer.
