Well, I know of the option to favorite stories, but often I don't realize a story is my favorite until it has had time to 'sink in,' so to speak. Also, sometimes I remember a small detail of a story and want to revisit/re-read it, but I have NO idea of the name until I see it. I think an option on the search page would be spectacular, but I understand that you can only do so much with things like that.
OK, thanks for explaining why you wanted it. It's always useful to understand the underlying requirement as that usually plays a major part in deciding how best to tackle the problem.
Providing the ability to search for items which you have read could be done but it would need to be done (in terms of the coding) is an entirely different way to the other searches. However, the results wouldn't be presented in the order in which you'd read them and so if you'd read a large number of stories it's not likely to solve your problem of remembering what it was you were reading.
Anyway, I'll have a think about it and see if I can come up with a better way of tackling it.
