It would be great if there was a way to highlight cards one by one in decklists, causing them to look similar to the way cards appear when they are not yet legal, with a colored border. For me, the most frequent use would be when cutting cards from decks. Being able to highlight all the cards I definitely need to keep would help make it easier to see which cards are left over. A show/hide highlighter option would be great too!
Thank you for the great site!
