r972 seemed to enable the TinyMCE "advanced features" toggle which brings up the extra formatting option.
I'm on the latest release and it seems to have vanished... or is it just me?
EDIT : Looks like something got rolled back. Line 32 of tiny_mce_config.php is :
$mce_buttons = apply_filters('mce_buttons', array('bold', 'italic', 'strikethrough', 'separator', 'bullist', 'numlist', 'outdent', 'indent', 'separator', 'justifyleft', 'justifycenter', 'justifyright', 'separator', 'link', 'unlink', 'image', 'wp_more', 'separator', 'spellchecker', 'separator', 'wp_help', 'wp_adv_start', 'wp_adv', 'separator', 'formatselect', 'underline', 'justifyfull', 'forecolor', 'separator', 'pastetext', 'pasteword', 'separator', 'removeformat', 'cleanup', 'separator', 'charmap', 'separator', 'undo', 'redo', 'wp_adv_end'));
when it should be as it was in r972:
$mce_buttons = apply_filters('mce_buttons', array('bold', 'italic', 'strikethrough', 'separator', 'bullist', 'numlist', 'outdent', 'indent', 'separator', 'justifyleft', 'justifycenter', 'justifyright', 'separator', 'link', 'unlink', 'image', 'wp_more', 'separator', 'spellchecker', 'separator', 'wp_help', 'wp_adv', 'wp_adv_start', 'formatselect', 'underline', 'justifyfull', 'forecolor', 'separator', 'pastetext', 'pasteword', 'separator', 'removeformat', 'cleanup', 'separator', 'charmap', 'separator', 'undo', 'redo', 'wp_adv_end'));
Guess I should raise a trac?
