Suggestion for better layout of individual threads

My suggestion is to keep the original post, or the first post, which is created by the original poster or OP, always at top, even when we change the pages in a thread.

currently on a thread, there are usually multiple pages, but the first post or original post is only visible on the first page, if we go to the second page, it disappears. i find it very difficult because I usually have to go back and forth to refer to original text.

this will also help staying on topic.
