From the answer at https://piklist.com/support/topic/editor-field-not-saving-data/ I got the impression that I could override the WordPress textarea meta box for post excerpts with a Piklist editor meta box.

Here’s my metabox file:

<?php
/*
Title: WYSIWYG
Post Type: post
Description: enables TinyMCE editor for excerpts
Priority: high
*/
  
piklist('field', array(
	'type' => 'editor'
	,'scope' => 'post'
	,'field' => 'post_excerpt'
	,'label' => 'Excerpt'
	,'options' => array (
		'media_buttons' => false
		,'teeny' => true
	)
));

Unfortunately it doesn’t change the Excerpt box. I tried removing post type support for excerpts in hopes that would remove the WP box … which it does. But it also evidently prevents Piklist from creating its box.

add_action( 'init', 'remove_post_excerpt' );
function remove_post_excerpt () {
	remove_post_type_support( 'post', 'excerpt' );
}

Suggestions? Thanks!

p.s. tried this on 0.9.4.26 and on beta 0.9.5v
