Recently Microsoft added more choices when adding a Web Part to SharePoint Online Modern pages.
We now have the “Divider” and “Spacer” which control page layout with either a horizontal rule (Divider) or white space (Spacer) between other web parts. Simple but helpful addition.
Also, Modern pages now include a “Promote” button that provides a right task pane with options to Add to Navigation, Post as News, or Email to inform a wider audience and build traffic. Cheers!
