Thanks for the kind words! So awesome that you are sharing the tools with others, I hope the rest of the team liked it too :)

It is so cool to see the tool in the front page of HN! We got an article published in css-tricks on Thursday about why we think generators are good tools for learning https://css-tricks.com/layoutit-grid-learning-css-grid-visua...

We open-sourced Layoutit Grid just a few weeks ago. There is still a lot of features we would like to add to showcase even more how powerful CSS Grid is. In case someone wants to help us out! https://github.com/Leniolabs/layoutit-grid
