Though it seems any significant revisions are unlikely, let me post an additional feature request:

- object dimensions: when an object is selected, we should get in addition to the bounding box dimensions geometrically useful values. For a line, the actual length of the line should be shown to allow us to skip manually computing sqrt(a^2+b^2). For a shape, the perimeter of the shape and the area of the shape ought to be displayed or reachable somehow. I had these features in my favorite lamented graphics environment, Deneba/ACD Canvas, since around the turn of the century. Thanks for your consideration.
