Event details
When a project has many tasks, it would be very useful and convenient if one could select the desired hierarchy level to display, e.g., Show Outline Level 1 = main level tasks, and so on.
This same functionality has long been available in the MS Project and Project Online / Project Web App.
E.g.
Show Outline Level 1
Show Outline Level 2
Show Outline Level 3 etc
Show All Levels
Or the ability to quickly expand or collapse "All Tasks" would also be a helpful start.
