The post was talking about navigating the posts in this forum. Ken mentions the NR google home integration topic which does, indeed, have over 250 replies on it.
As DCJ points out, there is a way to conveniently navigate through the replies. And also, rather than having to drag that slider, you can click the timestamp at the bottom (where it says 9m ago
in Dave's screenshot) and it takes you right there.
@shrickus if you have ideas and suggestions for something else, please start a new topic in the #development:feature-requests category so they don't get lost in this unrelated topic.
I have moved this topic to the #meta category as it is regarding the forum and not node-red.
