Yea, I was inspired by it but with another layer of abstraction. I wanted every element is able to have any style the user wants and hovering over elements will show spacing colors like the dev tools (I find it useful and haven't seen another site builder that does it).

I will definitely add some kind of onboarding, thanks for the suggestion. I just don't want it to be too heavy. I always felt like other users are like me and just skip all tutorials and start playing with the platform, but I'm starting to think its too complicated for that.

Thanks for the great feedback.
