I intended to use the plugin since numeric slugs (like http://nirantar.org/1006) doesn't work with WordPress pages. I saw many problems with the plugin:
- The option to add the custom permalink doesn't show up in the Post/Page edit form, though it does show on other taxonomy like Tags or custom taxonomy (created by EG-Series plugin, for example). I had to add them using custom field.
- The Admin page does show all the pages having custom permalinks but the permalinks don't work at all and throw 404.
- In addition, all my existing Post permalinks stopped working and I had to disable the plugin eventually.
