Hello. I have this same question, but with something added. Since the developers don't include an option to delete old reports and since Martok indicates they are saved in case they need to be referred back to, my question is this:
How would one search through hundred of old reports for that one that might someday be needed to be referred to? I see no way to search through pages of old reports and if I can't, then there really is no reason to keep them, is there?
