I love the corner tool, and the range of corner options.
Is it possible to add another option for corners based on conic sections, e.g., ellipse, where the length and width of the ellipse can be adjusted? Something along the lines of the rounded corners of the iOS icon mask.
It would be great if this could also be added to the rounded rectangle tool as an option for creating icons. Although Apple apply the mask to the icon, it's useful to be able to reproduce it when designing, to see how the finished icon will look.
Also, an offset tool would be useful for offsetting or insetting, similar to what CAD apps can do. The expand stroke tool is one way to achieve this, although it does break the curve up into lots of smaller curves.
This explains the elliptical corner curves and what I mean by insetting:
