Automatically expands the next adjacent page when moving a page in Page List.
As you are moving a page in Page List, if you position the yellow move placeholder above a Page List item for a configurable period of time (default is 1000 milliseconds) then that item will expand, allowing the moving page to be dropped as child page.
In the module config you can set the delay before the Page List item adjacent to the move placeholder will be automatically expanded.
If you want to restrict the module functionality to only certain roles then create a new permission named page-list-auto-expand. If that permission exists then a user's role must have that permission or the module will not have an effect in Page List.
