In case you've been hiding under a rock for the last year (and I wouldn't blame you if you were), the hot new component being bundled with Drupal 8 is a built-in layout system called "Layout Builder". For those who've always wanted magazine-like layouts without the overhead of a heavy third-party solution like Panels, this could be your dream come true.
If you've followed my blog and/or work in the past, you'll know that I've been a big proponent of Paragraphs, and I built out the Ivan Allen College of Liberal Arts' Drupal 8 infrastructure on Paragraphs. That was not at all a bad decision at the time - I did start that work nearly five years ago in Drupal 7 (before Drupal 8 was even released) and Layout Builder itself did not become stable until late 2019.
With everyone talking about how cool Layout Builder is, I finally sat down at the start of this year and began trying to learn how it worked, so I could see how readily I could port over some of my existing Paragraphs based layouts. I'd put a lot of time and effort into those layouts, and I really hoped I would not have to start over from scratch.
