Blog Comments – author name and format

Hi @Sven
I am wondering if I create custom blog comments, is it possible to add line breaks to comments?
And secondly, is there a way to refer to the FIRSTNAME or NAME of the post author? EG %First_name% or something like this?
It would be great to do both of these for Blog Comments.
Here’s an example comment that we could form if these were enabled/possible:
