It would be great to promote a page as it's own Section rather than under an existing Section.
By dragging a page to the Section panel, an option to create a new name for the Section or remain the same as the title of the Page. Any sub-pages also get moved to the new section.
Sometimes it's quicker than having to create a Section, then drag the page.

+1 from me.
Rearranging pages and sections hierarchy would improve productivity.
