Is there any way to get the plug-in to act like default WP.
How to add excerpts to posts
To add an excerpt to a post, simply write one in the Excerpt field under the post edit box. An excerpt can be as short or as long as you wish. Usually, given its purpose, a couple of sentences is fine. If adding the excerpt manually, you may use (some) HTML formatting and the tags will not be stripped.
Excerpt, automatic excerpt, and teaser
The manual WordPress excerpt is often confused with the automatic excerpt or with the teaser (the part of a post that appears on the front page when you use the More tag). While both are related to the manual excerpt, they are different from it.
The relationship between the three is this: When a post has no manual excerpt and the post template uses the the_excerpt() template tag, WordPress generates an excerpt automatically by selecting the first 55 words of the post. When the post template uses the the_content() template tag, WordPress will look for the More tag and create a teaser from the content that precedes the More tag.
If using content=yes, WordPress (and Catlist) default behavior displays everything in the content area, preserving HTML formatting. The only exception would be if <!--more--> tag is used.
If using Excerpts, WordPress default behavior, is to first check if there is a custom excerpt if so, display it and preserve (some) HTML tags. If there is no excerpt it pulls from content stripping HTML tags. Unfortunately this is not what Catlist Version 0.30.3 does. :(
It seems the plugin Version 0.30.3 either keeps the HTML tags or strips them. Where-as the default WordPress Excerpt behavior, keeps certain HTML tags in the Excepts and if there is no excerpt it takes the content but strips HTML tags.
The problem with this is that if their is no excerpt and you ask to keep HTML tags it displays images etc.
