Closed reports are not helpful after a period of time.
In my board I don't see why closed reports belong to 1 year ago (for example) should be kept, the only thing they do is using storage space! So I try to keep the ones belong to 30 days and less, and delete the others. I don't actually remember to do that every day or even every month! And when I do remember there would be 30-40 pages of closed reports that I should delete, which is really hard and give me headache!
So, I was thinking if there is a feature to auto prune closed reports, from those who belongs to more than a month, it would be very useful.
