Thanks for your feedback!

I just pushed a video to the homepage, there was already a live demo though, it was actually quite simple to implement (mostly gate a few things). There was a bit of a fear that agent somewhere out there would still be listening though...

I think a diff is an excellent idea. Perhaps with the ability to remove specific changes and switch before/after.

In terms of Tailwind, I'm thinking about a token/strict mode which would detect Tailwind classes and CSS variables. It wouldn't expose these in the sense you had to apply each one manually, but if you were for instance changing padding, it would snap between all your pre-defined tokens.

For the draw feature I think I'm just heavily Framer-pilled and it lets you pre-determine a rough width and height within a stack. But perhaps there's space for a click-to-add also with minimum dimensions.
