Where is the “New Section Group” feature in OneNote UWP?
The “New Section Group” feature of the OneNote UWP is not easy to find.
When the section list pane has blank space, right-click on the blank Space.
In the pop-up menu, you can see the new “New Section Group” menu item.
If no blank space in the section list pane, you cannot find the new section group from this location.
There is a "+ New Section" button at the bottom in the section list pane.
The button has a menu item named “New Section Group” in its right-click menu.
