That is exactly how we want to use:
Roadmaps to track all our team’s projects
Atlas to keep our stakeholders and team members updated on progress.
Our "Caveat" is that our Projects goes through specific stages - which we capture in a singular Kanban.
So, when you use the "Timeline view", we can have the stages in a column, but you can't have the "overall project status" from Atlas in a column. (only in the kanban board)
