This plugin has been used by our company for a while to link all of our related news, articles, and more by tags and the added option of thumbnail is a very nice feature to have.
We use a multilanguage plugin called qTranslate and had to use a patch that we had to find out on our own to get it to work with this plugin, so that was the downside. But that solution is now public in the support forum here.
It would be great if the developer just included this patch in future updates because having compatibility with qTranslate is a feature many people are looking for, and will make our lives easier so we don't have to patch the plugin manually each time it is updated. =/
