WordPress Widgets are really great to keep the elements on your site modular and reusable. They have the option to have their title in them if you want to. However, this field is optional, and you leave it empty for those cases you don’t wish to display a title in the frontend. What about those times you have to stack many widgets into a sidebar without titles.
WordPress by default only includes the widget type as the name of the widget in the title bar when the title is not included, making it impossible to have an accurate reference of the function of that specific unit. That is where this plugin comes in handy.
This plugin will create an extra field on every widget in the Appearance -> Widgets area (not available in the Customizer) named “Widget title” that will allow you to have a custom title for that Widget. You can just leave this field blank when you want the default titles from WordPress.
Enjoy!
