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>

I’ve optimised the plugin for a 468×80 pixel ad. Other sizes will work but may require your own CSS tweaks to make them look right.

P2 Header Ad

Works just fine! I'll use it for internal important notifications but definitely saved me some time for writing this feature myself :)

Nice!

Places a 468x80 pixel advert inside the header of Automattic's wonderful P2 Theme.
