Matthew Spaur (ID: 0000000b4e261139) Voted 5 ★ - Updated 01/12/2021 Just found this, could be in love! I was looking for an easy tool for storyboarding a novel. Most novel storyboard run horizontally. Was thinking about making a board in PowerPoint, thought of Trello, and wonder it there was a way to make lists run horizontally. Bingo! I'm surprised that this hasn't been folded into Trello as an official feature.
