By default, WordPress only allows 30 custom field names/keys to be listed in the dropdown selection ‘Name’ field when writing a post or page. If you, or the plugins you use, make use of a lot of custom field key names, you may surpass the default limit resulting in some custom field keys not being listed. This may force post authors to manually type in custom field key names if they aren’t listed, which increases the chances for naming errors (typos, or not using the precise key name that is needed). This may also cause some authors concern wondering where previously used custom field keys have gone since they aren’t listed.
This plugin increases the limit to 200 custom field key names.
There is no settings page to customize the default value. If you’d like to list some number of custom field key names other than 200 (say, for example, 100), you can do so in either of two ways:
<ol>
<li>By editing your wp-config.php file and at the end adding a line such as: 
define( ‘CUSTOM_FIELD_NAMES_LIMIT’, 100 ); 
-or-</li>
<li>Somewhere — ideally in a mu-plugin or site-specific plugin, or less ideally your active theme’s functions.php file — hook the ‘c2c_list_more_custom_field_names’ filter and return the number you’d like to use: 
add_filter( ‘c2c_list_more_custom_field_names’, function ( $limist ) { return 100; } );</li>
</ol>
Note: This plugin has no effect for users who make use of the block editor (aka Gutenberg) introduced in WordPress v5.0 because that editor does not directly expose custom fields in the interface.

Admin Quick Jump is a very simple plugin that adds a dropdown list to the admin edit-post area. The list contains posts of the same post_type as the one you are currently editing, and allows you to quickly jump between other draft and published posts. This is much less time-consuming than navigating back to the posts list and choosing the post you need.
<ul>
<li>Perfect for quickly jumping between editing posts, pages and custom posts.</li>
<li>No plugin settings page required, simply install and activate the plugin.</li>
</ul>

When I need to edit a bunch of pages, this plugin saves me a lot of time. Instead of going back to the page list each time, I can just go directly from page to page. Also works for posts and custom post types. Love it.
