Do you write posts in different languages that have different directions? 
This plugin enables a feature in the post editor which allow writing texts in Left-to-Right and Right-to-Left directions in the same post (or page) so you can write in English (and any other LTR language) and also RTL languages like Arabic, Persian and Hebrew.
Simply look for the new buttons added to the post editor after installing the plugin. (See the screenshots for better understanding)
