Just like how the individual comics have with Red, Green and Yellow markers in the upper right. I think it would be great to have on a folder containing a number of comics to show the same way so if i read one comic I'd love for that folder to now have a Yellow marking on the upper corner. When it is done Red.

Bonus feature would be to optionally hide folders & comics that have been read.

Being able to do both of these things when using a server would be ideal. I don't currently keep any comics local on my device they are all on a local networked server.

Thanks for the suggestions, all of them are already in my TODO list.
