Easy tuning tree comments

I propose such an idea for the visual interface of blog posts:

Imagine a comment tree on any post, take any comment from this tree that is not on the first level of nesting. So, the idea is that in the title of this comment was a button-link that allows you to hide all adjacent (relative to this, at this level of nesting) comments.

The point in improving readability is that when you read a comment thread and by clicking on _vremenno_ you can’t see parallel branches, then finding the text of the previous comment is much easier than scrolling the page.

I came up with this idea after reading comments in this thread: habrahabr.ru/blogs/hr/38381/#comment_909155

First you read the comments of the first branch, started by ifesdjeen, and then you reach the branch started by nekt. Maybe I have memory problems, but I can not immediately understand what he is responsible for, and I have to scroll the page up. And then down.
