We'll create fresh WordPress site with Indic installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Indic enables Indic transliteration in the visual editor. In order to use it just choose the preferred script from the dropdown in the visual editor.
The current script is saved in a cookie and it is recovered the next time you use the editor.
Behind the scenes the plugin uses the Gamabhana library.
