Filter for Completed tasks
Can a filter be created to search across completed tasks? I know how to view my completed tasks from the 'completed tasks' link in the top right corner, but I'd appreciate being able to filter completed tasks similar to active tasks. For example, rather than the top down view given by the 'completed tasks' link I'd like to plug in a filter for "completed, btw 05/01/2014 and 06/30/2014" as easily as any other filter. That would also allow for creating hard filters for things regularly used like "completed, 7 days", "completed, 30 days", "completed, :to others:, 7 days", "completed, :to others:, 30 days".
