Hi @janpeeters ,
With the new features in recent versions of Obsidian, I’ve changed how I manage titles in my notes:
Now that there is a built-in feature for displaying the note title at the top of the page, I no longer use note titles for my individual notes. The automatic display is more convenient for me, especially because it stays in sync with the page’s filename.
Now that the export-to-PDF function also supports including the page title in the exported document, I don’t need inline titles for printing anymore either.
An added benefit to this is that embedding pages becomes more convenient too – embedded pages no longer cause a giant header to appear in the parent page. 
I hope this is helpful,
Craig
