I was on the fence until i tried the free trial and boy the UI is superb! Clearly a lot of effort has gone into making it an amazing user experience so hats off to your design team! I have tried a few other PM tools and the experience with this is way ahead of the curve.

I do hope that a Mind Mapping tool is created soon as well as better integration with Google Docs so it doesn't open in a new window.

But I think this has huge potential and will be one of those LTD's you wish you were able to purchase if you missed out.
