I have added the Roadmap mockup now, and I was wondering if you like the design and layout of the page? You will need to view it on a desktop / laptop screen. It doesn't display nicely on mobile right now, but that can always be fixed. I just wanted to get some first impressions before I spent more time on it.
Also, I understand you may not want to list dates here, and so they could be removed. And instead of displaying the year in the circle, it could be something like a checkbox icon, and it gets checked when a milestone has been reached.
Let me know your thoughts, thanks!
