This plugin uses WordPress’ ability to return feeds, to get the last X number of items from any RSS feed. Display the last few items from any RSS feed of your choice. For example, your Twitter feed, or another blog or forum that outputs a RSS feed. Any RSS feed can be grabbed. Call it in your footer to list your last few tweets, or your sidebar to showcase content from another one of your blogs.
Uses <code>fetch_feed</code>, which was introduced in WordPress 2.8. Works and tested in WordPress 3.5 and above. By default, feeds are cached for 12 hours. You can choose a shorter (or longer) cache time.
Feed items are wrapped in a div tag, with class “jpgetrssfeed” so you can style the output in your CSS file. The items list is surrounded by <code><ul></ul></code> tags, with each feed item listed in a <code><li></li></code> tag. However, you can specify a new CSS class to style output differently for different feeds.
You can output the feed item description along with each feed item link.
A button is added to the post editor toolbar so you can insert the shortcode in your posts or pages.

Make sure you go to the plugin settings page after installing to set options.
