Absolutely the most amazing plugin on the market!! I was a little hesitant at first with the high price of the developer license but it is way worth it and I will never regret it as this plugin does more than you can imagine but the best part is the support! I have never seen a plugin author be as supportive as Tareq is! He will do everything he can to ensure the plugin works to your needs on your install.
Seriously, don't waste time considering the plugin, just buy it ! You will find so many different uses and ideas to implement on multiple single installs and even multisite networks (which is what I use it for)
