I can set the Grouping to Ungrouped and Sort by Flagged but it doesn't change anything.

The Flag Filter is set to Any Flag State because I want to view all my tasks but have the flagged ones at the top.

Not sure what you mean by dragging the whole group to a spot in the sidebar. I do not want to move anything, just get an overview of my projects and tasks in the library *and* have the flagged ones at the top.
