Without getting too much into graphic design software, it can save a lot of time to be able to create a polygon right in IF. You could choose the number of sides, then create/resize the polygon on the canvas.
Also, something to free-form create a polygon would be neat. Like the pen tool in photoshop, you could plot points and straight lines will connect between each point… and the ending shape is filled in with a color.
Does anyone else think this would be helpful?
