I saved more than a dozen cards in one day, but i'd like to read thoroughly just three or four of them. I'd like to have a way to put a Star or sthg similar to some cards, to remember that they are in my "Reading List". I thought of using an extra tag (like "to read tomorrow"), but a star could be quicker and smoother. Similarly, i'd like to have a way to identify more quickly the cards where i have made highlights.
