This seems pretty cool! As a dev who is, for lack of design resources on my team, frequently asked to pretend to be a designer, this could very much come in handy!

That said, the real value to me would be using this tool to make medium-fidelity mockups that look like my existing site. It looks like maybe your templates would allow me to make mockups in Noya that match my existing colors/etc, but I'd be coupled to ChakraUI. If the pre-existing components from my pre-existing site don't match Chakra's components, it sounds like I'd be out of luck?
