@Dan_Olson Dependencies in instagantt actually work pretty well: If you move interdependent tasks, the entire link chain shifts. The due dates in Asana are also updated. Worth checking out!
Multiple dependencies are however missing, and a meaningful way to use milestones.
For your upcoming timeline PLEASE include dependencies - it is absolutely essential!
Also: Workload management is possible but not great in instagantt. Hope you are looking into that future for the timeline as well?
