The reason I said “define main page” is that it’s what I believe is the main page that these ideas seem most helpful to address, in my experience. So I wondered if we’re “on the same page” about what is the “main page”?
Many people have observed before that they could get a sidebar only when on the search page, when this stuff happens, just like you observed.
When I have the problem I just know that space is not adequate for information and you have to whittle down the info to as little as possible. Even when I had whittled it down in the past and the problem seemed solved, I’ve had to do so again by using additional options when it recurs.
You’re right. I can get more articles on the main page by switching “Brevity” from “headers” to “text”.
