Hello, I would like to draw extensible hook arrows in the graphics module, for example, the ones in the following diagram.

For now, there seems to be no option for such decoration of arrows. Any help would be appreciated.

# Hook arrows in the graphics module

I thought about it a bit but I did not find a solution. One can with a bit of patience prepare a macro using a smooth curve, but I do not know how to integrate it in the drawing tool so that one can insert such an arrow with, say, two mouse clicks.
