I play the MTG magic plugin, and I play multiple formats of the game. I have run into the problem where my decklist goes off my screen and I have to constantly browse to find the deck I want to play.
My idea is maybe being able to add folders into the deck creation aspect of the plugin. Meaning I could have a folder for all my casual, modern, legacy, FFA decks to go into. That way I can easily organize my decks and easily find them when I want to play a specific format.
