| /** | |
| * | |
| * This plugin provides an initial foundation for replacing the default WordPress admin dashboard. If you have a background in object-oriented programming, | |
| * you can create a subclass to customize and override the set_the_title() and page_content_callback_fn() methods. | |
| * Alternatively, if you're not familiar with object-oriented programming, you can modify the set_the_title() and page_content_callback_fn() functions according to your requirements. | |
| * | |
| * Modify the user redirection to the custom dashboard by adjusting the capability property for specific users. | |
| * And add the capability property if you want to remove this custom dashboard and back to the default wordpress dashboard | |
| * | |
| * Remember: To ensure the uninterrupted functionality of this plugin, simply place this file into the "mu-plugins" folder within the "wp-content" directory. | |
| * If the "mu-plugins" folder is not present, you can easily create one yourself. | |
