It isn't clear from the article if this is something you need to enable or if it just magically starts happening when you're on a new enough version. I see from the comment above mine that "there's no option to disable" implying that it's just the way excel will work going forward.
I know some long-time users may dislike this but it's going to be a huge benefit for me. We go through certification processes that are done in Excel workbooks and each line can be as large as half a page. It's super painful to scroll through these as you feel punished for wanting to just know what the contents of one line above might be since the sheet might scroll a huge amount. It's a small thing but a repeated annoyance that makes doing the certification a real drag.
I'm on the insiders track already so shall try this out. I'll share it with some others at work who should definitely appreciate this too 😊
