I hope whenever I submit something to HN that 1) someone cares enough to be this critical\constructive and 2) I am adult enough not to take it on the chin and not get sulky. I'm most worried about #2

I am the OP and I would hate it if I had a few "this is cool" comments and no constructive criticism. I really appreciate it. When I first read some of the harsher feedback on here, it did feel like a punch in the face - I won't lie ;-) But then I took a deep breath and read it again objectively and actually tried to take it in. And 99% of what's here is excellent feedback. I wasn't expecting any responses, honestly - I can't believe it! ;-)

I'm not in a position to critique the product at the moment, but it looks like there's plenty of feedback for you to work through anyway. Good luck!

Happy you take it like that ! I wish you the best
