Hi Niklas, thanks for writing.
Yes, the mailing list is the only way to get onboard at the moment.
As for sharing designs with developers, that’s something we’re still exploring based on conversations with our initial customers. It could be code export, a richer programmatic interface (like an API or query engine), or something else.
Having developers open files themselves in Subform and manually click on on individual elements is something we’d like to avoid, as it doesn’t scale up to meet the challenges of building + iterating on real products.
Happy to chat more details about your specific needs and use cases, just send us an email: email@example.com
