Cannot create subtasks form TODAY view. Must go to project to create subtasks. Is there a better way?
This is an intended behavior as the today or other date-based views shows all tasks that match the search criteria on the same level and also contains tasks from different projects which makes it very difficult to know where exactly would you prefer to add a sub-task and what to do if the task below which you're adding it is originally also a sub-task within its projects.
That said, it's currently only possible to manage task structures from within their projects, but we'll look into making it possible from anywhere in the future.
