When I'm already requiring ideas portal users to signup with a user name and password, I'd like to be able leverage they existing access to Aha! to show them where their submitted ideas that have been converted to features are sitting on the product road map.
You can display roadmaps and notes in your ideas portal using custom portal pages with the Aha! Ideas Advanced plan. Share your plans with customers and internal stakeholders in one central place. Learn more.
One way to achieve this would be to create a notebook which shows a page with the ideas which have been converted to features, as a way to show your roadmap. This notebook could either be embedded as a web page, or you could email a link or PDF to your portal users.
Given this workaround, at this time, we are unlikely to implement functionality around this specific feature due to the current priorities and goals. However, we will keep this idea open to gather additional feedback to track the level of interest within the community.
