That is an often wished feature, if there is some reasonable way to 
implement,
such a feature would be welcome upstream.

At the moment we only have inline notes that allow to add stuff inside 
lines.
I think this needs extensions in KTextEditor.
It would have a use case for LSP things, too.

I like the idea of having smooth scrolling and the better showing of 
inline information.

I think both will take some large amount of work, or at least some 
clever approach to it,
but I think they would we very useful for a lot of people.
