Thanks!

Perfect! The old way was usable, but not user-friendly to 
non-programmers. :)

Very nice!

Looks good for me here on 2.8.16/Linux.

I thought I had a case where turning on "Curved arrow wings?" worked on 
a highly curved, multiple-point path with the last point's tangent 
handles moved around, but when that toggle was off the non-curved end 
arrow was at a funny orientation. But I couldn't recreate it later, so 
maybe it was user error. If it shows up again I'll try to capture it and 
send you an .xcf file.

Also, I like to run the script with "Use new layer for arrow?" turned 
off, and "Delete path after arrow was drawn?" turned on. That works 
perfectly (the path is removed from the Paths dialog box). But if I 
don't like the results and do Edit -> Undo Arrow, the arrow is removed 
from the image and the path returns to the Path dialog as the selected 
path, but the it (points, handles, path) isn't visible in the image 
window, and "Selection From Path" and "Stroke Path" are 
grayed-out/inactive in the Toolbox dialog. Even selecting other paths 
doesn't make them visible or "stroke-able". At that point creating a new 
path behaves normally, and the Paths dialog can then be used to switch 
back and forth between any of the paths and they become 
visible/editable/stroke-able as they are selected. It's not that big a 
problem, and the original script does the same thing. Maybe some problem 
with gimp-image-undo-group-start/-end, or a bug in the internal 
implementation of those methods.

Sorry for too many details, but I thought I'd describe what I found in 
my testing. Once again, thanks for all the work you've put into this 
very useful script.
