[Enhancement] Arrow in line

[gregoiregentil]

Great project!

Would it be possible to add an arrow on a connected line? In order to show the direction of the line.

More generically, it would be great to have an image or a svg that could be drawn in the middle of the line. The code would have to rotate the image to be parallel to the line.

Very sorry for the late response, currently it's not possible, personally I wanted to implement this feature months ago, unfortunately I don't have much time but I'll consider adding this when I have the time.
