I think it's more intuitive this way. When you draw a rectangle, you start with a corner point and then draw the width and height. With a circle, you go to the center and then draw it with a radius.
I think that's true only if one uses a compasses for circle. And that circle does not start with pen at centre. In easylang, it does.
In my opinion, the easylang positioning shoud not be based on any off-computer drawing process specific to the shape type, but on the result, consistently for all shape types. Only this meets e.g. the expectation that change to shape type retains position.

Question: why is rect not centered on pen, as is circle?
Because it has a width and height.
So does circle shape. Yet it is centred on both, whereas rect shape is centred on neither.

I wish your project every success.
