I'm new to using Tasks on EN. I too like the idea of being able to add tags to tasks but understand it may be difficult given the note architecture. My workaround is to create a note for tasks within each project (=notebook) I'm working on. That way I can group by project in the task view. Not perfect, because if I add tags to other notes within the project they tasks won't group together neatly, but it provides one more level of organization.
