I wonder if the "Save" button is needed when creating a new Task in List View. I just created a new Task, assigned a Due-date and a Team member, and then submitted a couple feature requests based on my experience. I must have forgotten to click Save, as when I returned to the Project I couldn't find the task.
For me it would be fine if a new Task created in List View saved automatically. Then we could remove the Save button from this view.
Thanks for considering this request.
