Really cool idea, especially if you guys are going to build github for SVGs... but it looks like you guys have a bug in your process. Consider the workflow I attempted to do:

1. sign up 2. go through the little tutorial 3. get prompted to name a new project 4. do so, and it now feels broken (unresponsive) 5. navigate back to the project/:projectId page 6. click new design 7. select "blank" 8. get to a 404 page with the following url: https://inlinehq.com/projects/39653/designs/new?template_id=...

Also, the new design button is really unresponsive, please consider making that button aware if it has promises waiting to for your server to fulfill.
