[yxcvbnm]

In admin/edit.php, line 275-283, the settings for the admin CKeditor are set. i'd like to customize the editor settings, e.g. using Image, ...

Code:

if ($EDTOOL == 'advanced') {
    $toolbar = "
        ['Bold', 'Italic', 'Underline', 'NumberedList', 'BulletedList', 'JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock', 'Table', 'TextColor', 'BGColor', 'Link', 'Unlink', 'RemoveFormat', 'Source'],
        '/',
        ['Styles','Format','Font','FontSize']
    ";
} else {
    $toolbar = "['Bold', 'Italic', 'Underline', 'NumberedList', 'BulletedList', 'JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock', 'Link', 'Unlink', 'RemoveFormat', 'Source']";
}
