Redirect Redirection (Premium)
Here you can (pre-)order the premium version of the Redirect Redirection plugin, for which there is already a (very good) free version out (check it out in the WordPress Repository), however we're planning many additional cool premium features.
The price is discounted, as the premium version isn't live yet. You can also see this as a donation for our free plugin :)
By the way, if you have ideas what (additional) features the premium version of the plugin should contain, we're always happy to hear about them in the WordPress Forum.
