Dan’s Annotator lets logged-in users (and email based collaborators) highlight elements on any page and discuss them in threaded comments. It adds a floating UI to create, browse, and close annotation threads, plus @-mentions with email notifications.
<h3>Features</h3>
– Custom database tables for threads, comments, tags, and collaborators (created on activation). 
– Admin bar toggle to enable/disable annotation mode for logged-in users. 
– Front-end badges showing counts and a side panel UI for reading/posting comments. 
– @username tagging with autocomplete and email/admin-notice notifications. 
– REST API endpoints used by the front-end JavaScript. 
– Support for outside collaborators with email-based or link-based access.
<h3>Usage</h3>
<h3>@ Completion (User Tagging)</h3>
To mention a registered WordPress user in an annotation comment: 
1. Type <code>@</code> followed by the username or email 
2. An autocomplete dropdown will appear showing matching users 
3. Select the user from the list or continue typing their username 
4. The tagged user will receive a notification (admin notice for logged-in users)
Example: <code>@john</code> or <code>@admin</code>
<h3>@email Collaborators (Email-Based Access)</h3>
To invite external collaborators who don’t have WordPress accounts: 
1. In a comment, type <code>@</code> followed by their email address 
2. Example: <code>@john@doe.com</code> 
3. The collaborator will automatically be created and receive an email with a secure magic link 
4. They can click the link to access and comment on the specific thread without creating an account 
5. Email-based collaborators are scoped to only the threads they’re tagged in
Note: The magic link is unique and secure, tied to their email address. Enable this feature in Settings → Annotator → Outside Collaborators.
<h3>!@link Collaborators (Link-Based Access)</h3>
For lightweight collaborator access without requiring an email: 
1. In a comment, type <code>!@</code> followed by a name/identifier 
2. Example: <code>!@mike</code> or <code>!@designer</code> 
3. A token-based collaborator is created with a shareable link 
4. Copy the generated link from the comment and share it directly 
5. Anyone with the link can participate using that collaborator identity 
6. Link-based collaborators are also scoped to the threads they’re tagged in
Note: Enable token-based collaborators in Settings → Annotator → Token-based collaborators. This is useful for quick feedback without email verification.

Beckin

Beckin Post Notes gives editors a fast, private way to attach notes to individual posts, pages, and custom post types, right where they work. Notes are stored as post meta and only visible to users who can edit the post.
Why it’s unique 
1. Most “notes” plugins add global dashboard notes. This one is contextual, notes live on the post or page itself and appear in the list table. 
2. Zero clutter: no admin menus, no persistent banners, no database tables. 
3. Clean and compliant: sanitized input, nonces, capability checks, no direct SQL.
Features 
– Side metabox labeled automatically (e.g. “Post Note” or “Page Note”). 
– “Note” column in the list table with a note 📝 icon when a note exists. 
– New filter dropdown: quickly show only posts with or without notes. 
– Only users who can edit the post can view or edit its note. 
– Extendable: use <code>beckin_postnotes_supported_post_types</code> to enable notes on custom post types.
Extendable Example: 
Simply add a small snippet of code in a theme or by using a code snippet plugin
<pre><code>add_filter( 'beckin_postnotes_supported_post_types', fn( $types ) => array_merge( $types, [ 'your_custom_post_type' ] ) );
</code></pre>
