Location of new custom filter/folder when folder is selected

When a folder is selected in the list of Filters, and then a new filter or folder is created from the bottom left menu, the new filter or folder is located below, but at the same level as, the selected folder. In other words the new item becomes the next sibling after the folder instead of a child within it. I think it’d be more intuitive and useful for the new item to be created within the selected folder.
