WordPress plugins frequently become abandoned by their developers, and in-turn, develop security vulnerabilities. If one of these plugins is installed on your site, it will put your site at risk, without any warning or indication. Outdated Plugin Notifier is a lightweight and unobtrusive plugin that helps you stay aware of these situations. Outdated Plugin Notifier monitors your plugins and tells you exactly when each plugin was last updated by its developer. If a plugin has been expelled from the WordPress plugin repository, Outdated Plugin Notifier will display that information as well.
To use, simply install and activate the plugin. There is no additional configuration required. After, open the plugin admin page from your WordPress dashboard and you will see a new column displayed in the table: Last Dev Update. This column will indicate the last date the plugin was updated by its developer. If it has been several months–or years–since the developer last updated the plugin, you may want to contact the developer to confirm the plugin is still maintained. If the plugin is no longer in the WordPress plugin repository, Outdated Plugin Notifier will indicate so on the plugins admin page, and suggest you remove and/or replace the plugin.

Very handy during my annual plugin check.

It does just what it says

To the plugins admin table, adds a new column indicating the last time the plugin developer released an update.

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

Plugin Notes Plus

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.

Super useful plugin for multi-admin sites

Does one thing and does it well.

I was about to build something like this and was thrilled this plugin not only existed, but is very well done! Thank you!

Exactly What I Needed!

Adds a column to the Plugins page where you can add, edit, or delete notes about a plugin.
