If you're a marketplace author, you might be interested in this next WordPress plugin. November-released AuthorHQ is a WordPress plugin that introduces sales statistics and more into the WordPress dashboard. AuthorHQ also includes a lightweight support forum that allows authors to run a support website to help their buyers without having to provide endless pages of documentation.

If I were a marketplace author, trust me, i'd already have this download by now. It is a new plugin, but has still been featured on ThemeForest and already has a full five star buyer rating. It's currently available through CodeCanyon from $35.

360 Degrees Viewer

Ever wanted to show off a product on your site? Yes? Ever wanted to do so in three hundred and sixty degrees? Of course you have, and this next plugin can achieve just that. 360 Degree Viewer allows you to show 360-degree images on your WordPress site by compiling a number of angeled shots together. Not only can this be useful for products, but any type of stage-by-stage photo viewer including panoramic photos.

And it's all done through a shortcode.

The plugin, which has a five star buyer rating on CodeCanyon, is available from $10.

WordPress Theme Switcher+

WordPress Theme Switcher+ does what it says on the tin, allowing you to host multiple themes on your WordPress blog. Unlike a lot of plugins that do so because of user action, such as through a menu system or a URL parameter, WordPress Theme Switcher+ changes themes by triggers such as category, date or custom field.

The theme has a full five star buyer rating and can be had on CodeCanyon from $18.

Envato Items Info

Envato Items Info is a WordPress plugin that allows you to display information about an Envato marketplace item within WordPress, advertising a specific file. The plugin will allow users to see key information like number of sales, price and buyer rating alongside a link to purchase the item.

If you're promoting your own content, or are showcasing a marketplace item and want to pull in some more information about it, the plugin should be great. It comes with both a WordPress version and a regular PHP version, so you can use the features on a non-WordPress site too.

This particular file itself is fairly new, and only has 5 sales, although it does still hold a five star rating. It is available on CodeCanyon from $8.

Twitter Trending Widget

Twitter Trending Widget is a simple WordPress plugin which tracks the popularity of your posts based on the number of times it's URL has been posted to Twitter. This allows you to show which posts are being shared more and can act as a great way for your visitors to discover new posts.

The plugin has a five star buyer rating and is available from $7 from CodeCanyon.

Interstital Ads

Most of us don't like Interstital Ads but they can be effective and are sometimes necessary, so why not do it well? Interstital Ads is a WordPress plugin that allows your blog to host interstital ads that can be used to push ads, offer promotions and generally advertise other content.

The plugin, released in September, has received a five star buyer rating. It is available from CodeCanyon from $18.
