Feature request: bullnose end caps in Power stroke

[Alex Holden]

I've just discovered the Power stroke feature in the development branch of Inkscape and it is brilliant! Really useful for what I am doing.

A feature that would make it even more useful for my drawings is another style of end cap that I call 'bullnose'. I've attached a file that demonstrates the shape, created by converting a powerstroke curve to a path and manually tweaking the ends. Basically the line should end with a smooth node on the outside of the curve and a cusp node on the inside, with the smooth node set back a bit from the end. It would probably be useful to have a slider that lets you adjust how far back the smooth node is from the end (i.e. how sharp or blunt the point is).
