Flat view option for Tasks Board
Currently in the Tasks Board, subtasks are ALWAYS attached to tasks. Only main tasks are sorted in first instance. That makes it impossible to sort all tasks regardless if they are a main task or a subtask of any level. That's why I would like to see a toggle in 'Tasks Board > Settings > Display' with the name 'Detached subtasks'.
If toggle 'Detached subtasks' is ON, then:
Subtasks will be detached from their parent tasks and all tasks will be sorted as adjusted (e.g. by Due Date), no matter if the individual task is a main task or a subtask or a subsubtask (and so on).
If you are in "List" view, after each subtask title it needs attached the title of its parent task in light gray (e.g. "subtask title < parent task title"). Also, it would be nice to have an identifier for the level of the subtask.
If you are in "Table" view, a separate column called 'Parent Task' should show the task that is one level higher than the subtask. Also, it would be nice to have a column that shows an identifier for the level of the subtask.
The Kanban and Gantt view should be treated in a corresponding way.
