I am using Silverstripe CMS and want to customize back-end wysiwyg editor Tiny MCE. I want to add into editor my custom button with my own action.
I found on TinyMCE page how to add button (http://www.tinymce.com/tryit/3_x/custom_toolbar_button.php) but I do not know where in Silverstripe folder structure can I put this javascript to extend TinyMCE.
Can you tell please me where can I put this code ?
