The Small Heading For Post Title is a simple plugin for displaying subtitles before or after post title. It is a useful plugin for the websites 
such as news websites that display some small headlines or captions before or after the main title. This plugin adds a meta box to your page/post forms 
in admin panel and you can determine a custom text as the subtitle and position of the text, then it will be shown before or after the post title based 
on your choice.
Also, in settings page of this plugin, you can add some CSS codes for styling the subtitles and you can determine and control that subtitles 
are shown in which sections of WordPress (See screenshot images).
