Is there any chance you can create a version with transparent background rather than black, so I can use it easier with overlays in the software I am using, Zwift and RoadGrandTours. There are some workarounds with OBS software, but a transparent version would be useful.
Unfortunately, it isn’t possible to make a browser window transparent.
I think these function could be really helpful for all People who want to watch something different.

Or a progressive web app?

I have had just see https://www.youtube.com/watch?v=fNifsR93kAs and by 3 min it’s what we want.
And it seems it’s no more available https://addons.palemoon.org/addon/glassmyfox/

I never use > 10 year old software, nor do I use unsigned/not trusted add-ons, like that first theme that you mentioned.
Plus, I have a Mac, so it wouldn’t be of use anyway. BTW, that screenshot makes my head and my eyes hurt, but I suppose you’re trying to show what would be possible.
