Firstly, I'd like to mention the customer care - quick response from Nic on holiday period - did not expect it to be as fast and detailed! Wow.
I am missing (and he already attended to that) the ability for customers and other parties to comment inside the proposal which makes it slightly harder to communicate.
Also, it is not always easy to move objects to change the design.
BUT, in general, I love it.
Easy, intuitive, pretty and as someone who designs badly it helped me generate a clear and pretty proposal!
Bought Tier 3 and I love it
