Hi Mark and others,
I don't think this is currently possible in QGIS. But I think that there
is definitely a need for such a functionality. Directionality is
important in GIS and QGIS should some day provide a way to display arrow
heads and other markers at vertices, similar to the concept SVG supports
markers.
Also, in conjunction with GRASS, such a functionality is quite important.

One of the outputs from r.flow in GRASS is downslope flow lines.
Without arrowheads (or some similar symbol like that) at the end of
lines pointing which way is downhill, the lines become ambiguous.
Is there a way to draw these lines with arrowheads? Or some other
approach that might achieve this?
Mark
