Fineswap

This plugin will make developers and site builders (hopefully very) happy.
It enables site administrators to supply additional styles or/and scripts to 
be loaded alongside the theme’s resources. It will work regardless which 
theme the site is running, which makes it brilliant for adding custom 
programming and content blocks.
Styles and scripts can be either entered manually or loaded from 
external URL’s.

Custom Resources

Easily load additional styles and scripts (for both front and backend pages). Works by direct inline embedding or by using URL's.

“Read More Right Here” uses the jQuery framework already included with WordPress installations. RMRH hooks into the WordPress creation of the 
“more” link and adds a custom class. When your blog is loaded, all links of this custom class are modified to no longer send the user to that post’s 
single page display when clicked. Instead, the WordPress database is queried for that specific post, and all content after the  tag (i.e. only what you need) is returned. 
The new content is then immediately displayed to the user, inline with the opening content.
