Admin Starred Posts lets you mark posts, pages and custom posts within the WordPress admin with stars. 
This helps you highlight a post, or mark it so you remember is important.
For example, you might have tons of pages, but are always editing one or two. In that case, star those pages, 
and they’ll be easily recognizable in your list of posts.
If you’ve used Gmail before, you’re very familiar with this feature. Similar to that email client, this plugin 
let’s you click on a star in your list of posts, pages and custom posts to ‘star’ it.
The plugin works out of the box, but you also get some configuration options to help you customize it to your workflow.
Configuration Options
<ul>
<li>Rotate between 12 different “stars”</li>
<li>Drag and set the orders of your stars</li>
<li>Enable/disable this feature for any post type in your WordPress install</li>
<li>Decide whether you want stars to be visible to every one, or in a per user basis.</li>
</ul>
Other Features
<ul>
<li>You can display only starred posts by using the “Stars” filter available at the top of the posts list.</li>
</ul>
This plugin requires WordPress 3.8 or higher

Admin Starred Posts

Nicely does the job of marking like email inbox. Some feature enhancements like adding from post edit page with a note will be great. 

Excellent plugin


This plugin is so useful for managing site wide updates and status of pages especially when working with a group- which are done, which need attention, which haven't been started. I install it on every site I've ever worked on, so I'm probably responsible for at least a hundred of the active installations. Please keep it updated and tested!!


I absolutely love this plugin!

Mark posts, pages and custom posts in your WordPress admin; pretty similar to the stars feature in Gmail.

This plugin allows you to keep track of the status of your posts as you work through each phase of creating them.
<h4>Why Use Phases?</h4>
Phases helps you stay organized as you progress through the steps of creating your posts. The steps from start to finish may differ, but Phases lets you keep track of your progress at a glance.
By default, phases comes with To Do, Doing Done phases, but you can change this to suit your needs. For instance, if you’re entering content, maybe you want a Not Started, Rough Draft, Edited, and Approved phases for your posts; or, if you’re testing a site, maybe you want Untested, QA, QC, Final phases. The phases you choose are up to you!
You can also enable notes to keep track of why a post is in a particular phase. For instance, you could have a phase called Blocked and list the reasons each post is blocked, like “blocked because missing hero image, missing author bio, missing accurate pricing” and so forth.
