This would be a brush feature adjustment that is a bit more “free” and intuitive than our current ability to adjusted vector lines with the pressure curve. This tool would allow us to grab our vector lines and push and pull them from any point on the individual vector without affecting any of the other vectors in the document. After seeing Kyle Webster working in this way in Adobe Animate, I thought, “Surely we could have a tool like this in Designer that could be even better.”
