How do I activate the comment overview?

If a post has many comments, a comment overview can be permanently displayed. This shows in detail how the comments have evolved.

On the details page for a post, click on the three dots to the right of the "Latest comment" link in the bar where the comments begin, and the number of comments will be displayed. A sub-menu will appear allowing you to toggle the comment overview on or off. The setting will be saved and will appear the next time you reload the page.
