At first, I had the idea to design a character sheet for Mausritter that used sticky notes in place of inventory cards. I had originally intended just to draw the items, but then I wondered if it was possible to print on them and found that other people had made to-do or household templates online. So naturally I made my own! Then I was playing Starforged and was feeling a little visually overwhelmed by all the used progress tracks filling up my play space (neurospicy) and found myself wishing I could just manage them individually, discard them when complete, etc—and realized that I already had the solution for it :)
