[feature suggestion]Favorite marks on favorited comic

[gauraputu]

I see that ~~you could actually add a comic twice into favorite reading list~~(not true, it seems there's a double of the same comic with a different name on my main library), because there are no sorting options there's no way to know which comic added twice unless you personally compare it one by one. it makes comics in the reading list a mess to explore. so at least some kind of mark in the main library would be nice, a good sorting option would be great but I did read that it was very hard to implement.
