Take Notice lets you add one or more notice boxes across your entire site. For each notice, you can customize the following:
<ul>
<li>Whether to appear on all posts (of any post type)</li>
<li>Whether to appear on specific posts (of any post type)</li>
<li>Whether to appear on posts with certain terms (of any taxonomy)</li>
<li>Where to appear in the post (above or below the content)</li>
<li>Color of notice box (custom colors or preset palettes)</li>
<li>Whether to display the notice title with its content</li>
</ul>
Notices are a custom post type, so they can be managed and edited just like posts. You can add more than one notice at a time, and customize the above settings separately for each one. (See Screenshots for an example.)

Take Notice

Add notices to all of your posts & pages at once. Customize where and how they appear.

For me, it’s place to leave notes about future articles, possible topics, ToDos connected with that particular WP site.
