Wow, thank you so, so much! That means a lot, we had a great time putting this together and it's very gratifying to see that it's translating for folks. Thanks as well for your notes, they're definitely on our list of things to tweak.

Thanks for taking the time to leave such an encouraging comment, it means a lot. We're excited to keep improving as we go!
