Still the best professional task manager
There are some obvious shortcomings (tags, anyone ?) and others like Todoist might be catching up, but OF still beats the competition if you consider not only the lists of actions themselves but system and workflow integration as well.
Could make better use of typical mobile interactions (how about e. g. swipe to defer?)
