Mhh, I think something like this would be better handled by something like a Tampermonkey script that runs in your browser.

This would also work on any site then.

While writing this, I realized there probably is something like this already out there. And voilà, there is.

Depending on which browser you use (I use Brave), just install the Tampermonkey extension and then install the script (don't just install any script for hopefully obvious reasons).

I just tested it and it did exactly what you were asking for:

This might not work on mobile though since I am not sure if you can install browser extensions on mobile.
