Creating epics, tasks, and subtasks is largely manual and takes way too long. What we need is a “trello” like view with a swimlane for epic, task, subtask (etc) that you can then start to map out your tasks visually. This will help when writing an initial epic because you can create it and link it all up on this page and easily move things around and underneath it will be doing all the work of managing ticket types and relationships to other tickets.
This view would also be super useful when you want to get a high level view of your epics and what tasks they involve.
