I am still a bit new to Joomla and it's world, but I have to say it is a great! world to be in. I was looking for a tool where I could run database queries and show tables and the odd bar chart. Though there are a few out there, this has to be the best all rounder!
Not just the product, though that in itself is fantastically good, the price is amazing for what you get and the support is nothing less than excellent!
This is a top notch plug in and well worth getting!
