Plugin Notes Plus


Have you ever returned to a site that you built a while back and asked, “Why did I install this plugin?” This plugin provides an extra column on the Plugins page that enables you to add, edit, or delete notes about the plugins you have installed on a particular site. These notes are intended to provide documentation regarding why a particular plugin was installed and how or where it’s being used.


  • Add as many or as few notes as you need for each plugin.
  • Edit or delete notes as desired.
  • Select an icon to go with each note to quickly convey what type of content it contains (e.g., info, warning, link, etc.)
  • Format notes using basic HTML tags if desired.
  • Any links included in the note will be automatically converted to target="_blank"
  • Notes are added and updated via Ajax, avoiding slow page reloads.
  • Notes also display on the WordPress Updates page for any plugins that need to be updated.
  • A filter is provided if you would like to display notes beneath the plugin description instead of in a separate column.


  • Upon activating the plugin, you will see a new column on the Plugins page that enables you to add, edit, or delete notes about the plugins you have installed on a particular site.


  1. You can either install the plugin via the Plugins directory from within your WordPress install, or you can upload the files manually to your server by extracting the .zip file and placing its contents in the /wp-content/plugins/ directory.
  2. Activate the plugin through the Plugins menu in WordPress.
  3. Add, edit, or delete notes in the Plugin Notes column on the Installed Plugins page.


Can I display the plugin notes beneath the plugin description instead of in a separate column?

As of version 1.2.4, you can use the filter plugin-notes-plus_note_placement to move notes beneath the plugin description.

Here is an example of a snippet that places plugin notes beneath the plugin description. It can be added to your child theme’s functions.php. Without this, the note position will default to a separate column on the plugins page.

function pnp_change_note_placement( $note_placement ) {

    $note_placement = 'description';

    return $note_placement;

add_filter( 'plugin-notes-plus_note_placement', 'pnp_change_note_placement' );

Can I modify which icons are available to display next to plugin notes?

Yes, you can use the filter plugin-notes-plus_icon_options to modify the set of icons available. The icons must be selected from the list of available WordPress dashicons.

Here is an example of a snippet that removes one icon and adds an additional icon to the list of options. It can be added to your child theme’s functions.php:

function pnp_change_icon_options( $icon_options ) {

    // Remove key option
    unset( $icon_options['dashicons-admin-network'] );

    // Add smartphone option
    $icon_options['dashicons-smartphone'] = 'Smartphone';

    return $icon_options;
add_filter( 'plugin-notes-plus_icon_options', 'pnp_change_icon_options' );

Which HTML tags are permitted, and can that list be modified?

You can use the following HTML tags: a, br, p, b, strong, i, em, u, hr.

To modify the list of available tags, use the filter plugin-notes-plus_allowed_html. Be careful, however, to avoid allowing tags that could leave the site vulnerable to an XSS attack.

function pnp_change_allowed_html_tags( $allowed_tags ) {

    // Remove br from allowed tags
    unset( $allowed_tags['br'] );

    // Add img to allowed tags
    $allowed_tags['img'] = array();

    return $allowed_tags;
add_filter( 'plugin-notes-plus_allowed_html', 'pnp_change_allowed_html_tags' );

Where is the data stored?

Plugin notes and note metadata are stored in a custom table whose name ends in plugin_notes_plus. In the initial version (1.0.0), notes were stored in the options table. Version 1.1.0 was released to migrate existing notes from the options table into the plugin_notes_plus table. Upgrading to version 1.1.1 will perform a cleanup, removing any notes from the options table.

How does it work on multisite installs?

Each site within a multisite install maintains its own plugin notes. Additionally, the superadmin can maintain their own plugin notes.

Very useful plugin to note why a certain plugin was installed on the site and any additional context around it, for other admins. Helps in housekeeping especially when there are more than one admins that try different plugins and forget to remove anything that is not wanted.

So many times I went to go update a plugin and forgot I didn't because the update was broken. This plugin allows me to add notes to remind me of why! Perfect

This plugin is simple, lightweight, and effective. And it is highly needed functionality. Whether you are writing notes to yourself so you do not forget or leaving notes for a client, this is the answer.

I was just thinking - wouldn't it be great to add notes to plugins, then i'd know why I or other admins added plugins. Next thought; if that doesn't already exist we are making it. I rarely leave reviews as I'm too busy, but this is an essential plugin, especially for agencies, designers/devs & admins. The problem with unused plugins is ubiquitous - this is a simple and elegant solution. Once I've tested it thoroughly I'll be adding to our base build.

So simple, but brilliant. I make note of every plugin in use (and where). That makes it easier in the long run to decide if something is being used. Worked great on a multi-developer sight so we knew who was adding what, and why.
