Users appreciate this WordPress plugin primarily for its simplicity and effectiveness in organizing pages, child and parent pages, and hierarchical custom post types. It simplifies moving pages around, making it particularly valuable for page-heavy sites. The visual representation of the page hierarchy and functionality to handle widget behavior is also highlighted. However, some users have reported critical issues such as the editing/text area not responding to keystrokes in WordPress 4.9.1, problems with z-indexing in the drag-and-drop interface, and incompatibility with the Post Forking plugin on WP 3.6 RC 1. Despite these drawbacks, it is praised for saving time, being user-friendly, and well-supported.
