Tree structure of comments on Habré

Faced with the fact that with a large nesting of comments, it just becomes inconvenient to read them. So one branch can completely go to the right, and after its completion "in the air" will hang an answer to one of the upper messages of this branch. In order to understand what exactly the author answered, you have to put the mouse on his comment and scroll up the page - it’s good at least not to put a ruler on the monitor. It seems to me that it would be more convenient to use thin gray - almost imperceptible - lines to draw offspring-parent relationships for comments. And thin and gray, so that they do not interfere with reading and users pay attention to them only when they need these connections to establish a "father" comment.
