You’re able to create new branches by selecting the idea you want them to branch off from and then tapping and holding on a spot on the screen. Each branched off idea can be color coded, include photo and message, include a task or subtask, and sport an icon. You’re able to freely rearrange your ideas just by dragging them around the canvas.
