This is a plugin that will enable you to add alerts, info and similar chunks of text.
This is useful when creating tutorials and you want the reader to be notified of a change in code or something to check. Info blocks are used in technical Books when you want to point some information or you want the reader to read a part that is important to understand the next piece of code.
This is also suitable when you republish articles on your blog to inform the user on what has changed.
Info Blocks also allow you to change:
<ul>
<li>Background color</li>
<li>Text color</li>
<li>Padding (size and unit)</li>
<li>Dashicon Icon (or leave it off)</li>
<li>Icon Size</li>
<li>Space between the Icon and Text</li>
</ul>

This plugin allows developers to have at a glance information directly on the WordPress Admin Dashboard. From basics like domain and server IP to more advanced like registrar, expiration date, and page speed timing. Additionally, a second metabox is available which finds TODO comments in the theme and organizes them. It also allows for categorizing and prioritizing the TODO tasks.
