Thanks! We try to make our product as accessible as possible for anyone to use (or at least to test). It's good to hear that our efforts have been worthwhile!
The text says "Instantly generate dynamic documents based on real-time data." but when I changed the react code to give the QR code a red color and clicked render it took far longer, maybe 5-6sec to render again.
We'll adjust the wording until we have a faster renderer. Also, the playground might take a bit longer to render since there's a queue and it's been heavily used! We're on it, thanks!
