When using keynotes or other generic annotations, even text for that matter, it would be nice to set the default leader arrow head, but make it an instance parameter that you can cycle through various arrowheads for the same tag. The reason is that when you schedule a generic annotation(keynote) you don't want to have to make a new type just to have a diff. arrowhead. Then you have 2 or 3 keynotes that say the exact same thing, just have diff. arrowheads.

What do you guys think?
