Suggestions to enhance line and arrow drawing

[Alister Hood]

1. When drawing a line as an arrow, the start point is offset by maybe half the length of an arrowhead. It would be better if the start point was where you clicked, as you could position the arrow more accurately.
2. The polyline tool is fantastic. It would be great if you could add the checkbox to draw it as an arrow (I do realise the code could be a bit complicated to add the arrow just to the last segment).
3. It would be nice to add a second arrowhead checkbox to draw an arrow at the start of the line instead of the end. This would enable you to draw a line with an arrow at either or both ends.

1. Confirm arrowhead start point is offset
2 & 3 I will consider these two points, as well as perhaps a separate arrow tool
