Automatically turn all posts into excerpts of 300 characters and add a “Show More” link that will load directly in the page. If your post includes a picture, it will also obtain a thumbnail and place that at the beginning of the excerpt. Supports Infinite Scroll, too (assuming you manually enabled it on your P2 site)!
<ul>
<li>Shorter posts will be left alone, unless they have a picture</li>
<li>Posts with a picture will always be turned into a thumbnail/excerpt</li>
<li>Expanding or contracting a post will scroll to the top of the post</li>
</ul>
Planned:
<ul>
<li>Long posts with embedded video and no image include the video in the excerpt</li>
<li>Change the character length from the admin screen</li>
</ul>

This plugin allows you to set deadline for posts and list posts with upcoming deadlines via shortcode.
Plugin is intended to be used with <a href="https://p2theme.com/" rel="nofollow ugc">P2 theme</a> or <a href="https://geto2.com/" rel="nofollow ugc">o2 plugin</a>, but can also work without it – only P2/o2 spesific functionality is datepicker field added to frontend post submit area. Datepicker for setting deadline is also available in classic editor and Gutenberg.
Plugin also automatically adds deadline to the end of <code>the_content</code> output if deadline is set. List of posts with upcoming deadlines are cached to transients to reduce amount of databse queries in large scale sites.

Post Deadlines

As old as this plugin it is, it still works just as expected on latest version of WordPress and P2 :)

Works like a charm
