Extension summary
Create and adjust CSS Shapes values with an interactive editor overlapping the selected element.
Update 21 May 2015:
For polygons, unit-less zero coordinates will inherit the non-zero sibling coordinate unit instead of defaulting to pixels. Example 0 100% => 0% 100%
Shapes sidebar: New sidebar to the DevTools Elements panel called "Shapes" which offers controls to create and edit CSS Shapes values like polygon(), circle() and ellipse() on the selected element.
Polygons: Click the edges of the shape to add new points. Drag points to change the shape. Double-click points to remove them. Select the transform tool to move, scale and rotate the polygon shape.
Circles & ellipses: Drag the shape to move it around. Pull on the edges and corners to scale and resize.
