Am looking for ability to separate or more clearly delineate various web parts and their data from other web parts, but SharePoint Online does not allow this. you can add a line (oh that is just great), or you could add a text element with a repeating set of dashes or underline characters, or I could take a picture of a line and save it as a PNG or GIF file and then insert that.

I mean come on folks are we now going back to a CLI....
