Hats off to you on the implementation and for being so technically ambitious.<p>I&#x27;m wondering why you exactly decided to go this route? I was expecting your app to be very graphically intensive or have some other kind of demanding requirements. When I went to the site it appears it&#x27;s some kind of collaborative design tool? Not saying these tools don&#x27;t require a top-notch UI. Maybe for manipulating and scrolling&#x2F;scaling huge canvases? Coming from a mapping background, I can totally see this as something lacking in the browser. There aren&#x27;t many primitives for creating these kinds of image-based interfaces.<p>There&#x27;s certainly a trade-off between having super-fast performance and a completely custom rendering engine and adopting a not-often used delivery mechanism and stack (C++&#x2F;asm.js). I&#x27;d imagine it&#x27;s hard to find people who have all that expertise, it&#x27;s hard enough finding a good frontend dev in the conventional technologies of the web.<p>Good luck on your product launch, can&#x27;t wait to use your UI and play around with it.
