Ave Sodales. In our groups of "Ars Magica" we would find comfortable if on the characters Sheet next to each ability you can insert a control cell that the player can check in order to mark which skills has used during the adventure, so as to know in What skills you can spend the experience points earned at the end of the adventure. In fact, the game rules say that only the skills that have been used during the adventure can be increased. It therefore becomes useful to insert a way to mark the skills that were used during the adventure, such as a checkbox in the character's card. Is it possible to change the character sheets in this sense, please?
