Once you've located this widget, click on the down arrow indicated by the green arrow to see the widget settings. The title is the title which will be displayed at the top of the widget in the sidebar it is located in. The purpose of this widget is to display your personal posts. (You can find more information about widgets in general at https://codex.wordpress.org/WordPress_Widgets)  

 

     On a page on your site, where the SP My Posts widget is active, you will see two tabs. One displays your published posts, and the other displays your drafts. The entire widget is shown here in the green box. It can be used to navigate to individual posts, just by clicking on the links. The "My Posts" is just the title that was set. It is completely open to customization from the dashboard.

 

     In addition, there is a Drafts tab, which shows all of your Draft Posts. You can navigate to those by clicking on the tab highlighted in green. In addition, you can choose to trash any post listed, by clicking the delete button highlighted in red.
