OP view is useless.
I click on the Gardening thread and see one and a half posts, then have to scroll and scroll with ads, photos, breaking up the screen - when what I want to do is look at the page of Gardening and glance down the topics on the page until I see something I am interested in or am knowledgeable about, click on it and read.
If OP becomes the setting I will skip Gardening entirely as I don't have time to scroll and scroll. I am on a laptop. I will change to compact view but what why was it changed?
