upPrev is such a cool plugin to add to your website. Apart from the coolness factor, it’ll encourage your visitors to keep reading your good content. It works when your reader scrolls down your post or page and out flys a little box with your previous post title with a clickable link. In the plugin’s settings you can select your preferences – just previous or previous in category. Be sure to select the thumbnail too. You can see this plugin in action on my site here. Just click on a post, scroll down the post and watch for the fly-out in the bottom right-hand corner.
