I feel like the inserted text should be highlighted with a light yellow background or some indicator. Just appearing like that inline seems a bit funky or unexpected.

But I see there is a css class which is nice.

Just a simple rgba(x,x,x,0.5) where the x’s are the usual yellow height.

I prefer to leave the styling to the user, the library is intentionally minimally invasive there...

I agree with this. It would be helpful.
