Multi-segment (polyline) arrows #4
Description
Like in vector applications, where you draw vector shapes and each mouse click adds a vertex to a polyline.
This could be nice for when you don't want straight lines but you also don't want freehand drawing.
It would also make super long arrows that span multiple viewports easier to draw (because you can scroll mid-drawing)
Optional: use bezier curves instead of polylines to make it nicer looking. This would probably be too weird
