Please help me.
I like the way Talk pages used to look, and still look on English Wikipedia. On Desktop, mind you, not on Mobile.
In particular: load and present the entire page at once, allowing you to for instance CTRL+F text search anything on the page, in any section (except content manually collapsed by an editor, I guess). With zero need for the incredibly obnoxious requirement to first open up or load each talk section, common to social media sites like Facebook or Reddit! :-(
I have tried my very best to find ANY information on how to opt-out of the new look you have here on Mediawiki, and haven't found anything. Not even "it's not possible, we are forcing you to use the new look."
I have tried setting the Appearance back from Vector (2022) to Legacy Vector (2010). It got rid of some of the right hand stuff, but the "About this board" sidebar still remains. I can collapse it, but not get rid of it. I find it useless, but it's a minor annoyance and doesn't revert the big change.
I have tried disabling all the checkboxes on the Editing tab under Discussion pages (Enable Quick Replying, Enable Quick Topic Adding, and Show Discussion Activity), but still talk pages (like this one) STILL persists in using a graphically voluminous look that I find clearly inferior to the old "boring" look.
About the only other relevant difference between Mediawiki's Preferences and English Wikipedia's Preferences is the Threaded Discussion tab. But there I find nothing useful. I tried setting both values to zero thinking that might disable the new look, but that wasn't possible "Please enter a value no less than one".
What I find most frustrating, however, is how I can't find any help or documentation on this issue.
I didn't find anything in your FAQ. I tried googling various iterations on how to opt out of threaded wikipedia discussions, structured discussions, and flow, but found nothing.
