Reduce arrowhead size without offset

Hi All,

for my needs, the default arrowhead dimensions on curve objects (relative to the line thickness) are too large.

When I Edit an existing arrowhead Attributes, and reduce the Size (Length/Width), then a gap develops between the arrowhead and the curve.

One can fix this with adding an X-Offset in the Attributes, but then the end of the arrowhead is shifted with respect to the end node of the curve.  This ruins the use of Snap To for the end position.

Is there any workaround here?  

BTW: What happened to the older arrowhead "designer" box (e.g. CDR12)  where one could shift the nodes of an arrowhead...
