It immediately reminded me of VectorStyler’s Path Width tool. Both let you shape strokes visually instead of being limited to a uniform width, which makes it easier to create more natural or calligraphic lines.

VectorStyler gives you detailed control directly along the path. IllustKit takes a different approach, using an oval to control the stroke’s width and angle. Adjusting the oval lets you quickly change the weight, direction, and overall character of the stroke without rebuilding the path or fighting with anchor points.

This could be especially useful for lettering and illustration work. I could see a similar oval control becoming a useful feature option within VectorStyler’s Path Width tool in the future.
