We need an option to edit the shape of line and polyline end caps. I believe this is an issue that has already been raised ( wish #12512 if I'm not mistaken )
This is an essential thing and it shouldn't be too difficult to do.
One way of doing it is adding shape selection option to marker menu.
Or it could be done the way AutoCAD does it - by adding thickness setting to polyline itself along with placement options - inside, outside, center.
