@myoder, I understand you being grateful to him, and I would be too. And it is great that you wrote the letter.

My question is more about "had you not been so gracious, Quipol might have never happened".

A mockup software doesn't seem to solve any important pain that can't be solved without and yet I see a lot of mockup softwares being created.

So my question is more about, why is a mockup software so important to you? What did it help you do that you couldn't have done without?
