Users appreciate the CMS Tree Page View plugin for its ability to easily organize and visualize the structure of pages in a tree-view format, which is especially useful for sites with a large number of pages. They find it straightforward, intuitive, and time-saving with functional drag-and-drop capabilities. The plugin enhances the default WordPress experience by making it easier to find and manage pages due to an efficient search function and clear parent/child relationships. However, some drawbacks include the plugin not supporting blog posts, with some users expecting a category-based tree structure for posts. There are also reported issues in controlling the WordPress menu and minor UI usability concerns.
