Buttons “next branch” and “previous branch” in the comments

Each comment thread has its own topic, which is set by the first comment in it. When there are a lot of comments (like, for example, habrahabr.ru/blogs/copyright/110185 here ), there is a desire to read not all branches, but only on topics that are close to you. Now there is no way to quickly find the beginning of the next or previous branch, but I would like to have such an opportunity.
