WP Job Manager set TinyMCE to defaults (color picker, etc)

functions.php

<?php
// This is my own personal modified version that I recommend

add_filter( 'submit_job_form_wp_editor_args', 'smyles_wpjm_wp_editor_wp_defaults', 99999 );

function smyles_wpjm_wp_editor_wp_defaults( $args ) {

	$args['tinymce'] = array(
		'plugins'                       => 'charmap,colorpicker,hr,lists,paste,tabfocus,textcolor,wordpress,wpautoresize,wplink,wpdialogs,wptextpattern,wpview,image',
		'paste_as_text'                 => true,
		'paste_auto_cleanup_on_paste'   => true,
		'paste_remove_spans'            => true,
		'paste_remove_styles'           => true,
		'paste_remove_styles_if_webkit' => true,
		'paste_strip_class_attributes'  => true,
		'toolbar1'                      => 'formatselect,forecolor,bold,italic,removeformat,bullist,numlist,blockquote,alignleft,aligncenter,alignright,link,wp_adv',
		'toolbar2'                      => 'strikethrough,hr,pastetext,charmap,outdent,indent,undo,redo,wp_help',
		'toolbar3'                      => '',
		'toolbar4'                      => ''
	);

	return $args;
}

functions_wp_defaults.php

<?php
// These are the WordPress defaults (most stripped out by WPJM), this is really just for reference, I don't suggest using this one
add_filter('submit_job_form_wp_editor_args', 'smyles_wpjm_wp_editor_wp_defaults', 99999 );

function smyles_wpjm_wp_editor_wp_defaults( $args ){
	$args['tinymce'] = array(
		'plugins'                       => 'charmap,colorpicker,hr,lists,media,paste,tabfocus,textcolor,fullscreen,wordpress,wpautoresize,wpeditimage,wpemoji,wpgallery,wplink,wpdialogs,wptextpattern,wpview,image',
		'paste_as_text'                 => true,
		'paste_auto_cleanup_on_paste'   => true,
		'paste_remove_spans'            => true,
		'paste_remove_styles'           => true,
		'paste_remove_styles_if_webkit' => true,
		'paste_strip_class_attributes'  => true,
		'toolbar1'                      => 'formatselect,bold,italic,bullist,numlist,blockquote,alignleft,aligncenter,alignright,link,wp_more,spellchecker,fullscreen,wp_adv',
		'toolbar2'                      => 'strikethrough,hr,forecolor,pastetext,removeformat,charmap,outdent,indent,undo,redo,wp_help',
		'toolbar3'                      => '',
		'toolbar4'                      => ''
	);
	return $args;	
}

Above are two files functions_wp_defaults.php where I basically just set everything back to the defaults that WordPress uses (which most of them WPJM stripped out). I don't recommend using that one.

The recommended one is the functions.php where I added things like color selector, clear formatting to the top toolbar. You can easily customize these yourself by moving them around as you wish (or remove all together)
