Editing WordPress Plugins
Show/Hide Content at Set Time
Use a shortcode included in the plugin to automatically display or hide content on your posts and pages according to the time and date.
Global Content Blocks
Create tiny chunks of reusable content, including text, forms, and PHP code, and then add them to posts or pages with a shortcode or TinyMCE button.
Automatic Post Scheduler
Set an interval of time between each one of your posts and make sure that there is a proper time interval between each one.
Public Post Preview
Create a randomized URL that can be shared for public viewing before the post or page is published, so only users with the URL can view the page.
Restrict Author Posting
Restrict users to a single category using a drop-down menu in the user's profile. Restricted users will only be able to publish to the category they are assigned to.
Byline
Easily add multiple authors to posts in WordPress just as you would tags, and automatically replace the author link on the front-end.
Tabify Edit Screen
Choose which pieces of the WordPress editor to group together, so that it's a little bit more organized. Customize for each post type, and turn on or off with a checkbox.
Edit Flow
Manage a WordPress site with multiple authors, send notifications on post updates, comment on posts and pages, customize post statuses, and refine the post editor.
TinyMCE Spellcheck
Spellcheck used to be bundled with After the Deadline, before it became part of Jetpack. This plugin is a fork of that functionality to add it back to your WYSIWYG editor and can be customized for each user.
TablePress
Add or import a table from a variety of different formats, then add it to your posts and pages with the use of a shortcode. Uses Javascript for advanced functionality like sorting and pagination, which can be customized at output.
Post Forking
Create new branch of every post that you have and compare revisions, even between different authors. Then, you can merge together changes automatically. A good way to collaborate on and version control post editing.
Editorial Calendar
Manage your posts using a calendar interface. Easily drag posts from one day to another, schedule your drafts and view all of your upcoming and past posts in a full page calendar layout.
