<p>This plugin was created to allow any page to be viewable from the WordPress/MU Admin Panels. You can use it to view a page before you submit it or to just look at anything on your blog. The beauty of it, is that because it uses iframes you can have it show you anything on any domain! For example, I use it to keep track of my forums while I am writing a post/page and to see if I need to add anything based on the current discussions.</p>
<p>Those of you who use my <a href="https://wordpress.org/extend/plugins/new-bbpress-admin/" rel="ugc">New bbPress Admin</a> plugin might notice a few similarities between the plugins. The truth is that the functionality of the two is so similar, that the codebase is also 99.9% the same. The only differences are in the variables (so that both can be uses simultaenously with no problems) and some of the text, so that you can tell the difference between the two of them. There is no ill effect if both are used at the same time. Options entered in one will be kept separate from the other.</p>

Live Gold Price & Silver Price Charts Widgets

The plugin does exactly what it offers.

Yet, in my opinion, it is poorly implemented. The plugin merely includes iframe code from www.goldbroker.com instead of directly fetching the prices from an API and displaying it itself (without an iframe). 
(The same functionality could be achieved by copying the iframe code (with the url and the needed parameters) and pasting it into a text widget.)

Works, but bad implementation
