Not sure if there is a way to already do this, but what I was thinking would be very helpful is if the flags that are currently being used on single comics are also used on folders. The idea of being if I was to read one or more comics inside of a folder, the folder itself would now have a yellow flag on it and If I read all of the comics inside of that folder, the folder would now have a red flag just like it currently works with individual comics.
