Editing the tinymce editor (HTML Editor)

You may want to remove the button or add the feature inside your tinymce so it will suit with your need. It can be done easily.

There are 2 files: for Front End and Staff Panel.
Please refer to /gui/smarty_template/templates/. It will list both in Front and Staff directory. It is tiny_mce_include.tpl

    tinyMCE.init({
        mode : "specific_textareas",
        editor_selector : "mceEditor",
        theme : "advanced",
        relative_urls : false,
        theme_advanced_buttons1 : "bold,italic,underline,separator,strikethrough,link,unlink,separator,forecolor,backcolor,image,charmap,fontsizeselect",
        theme_advanced_buttons2 : "",
        theme_advanced_buttons3 : "",
