[Feature Request] Custom color for arrow circle

[Naamloos]

Is your feature request related to a problem? Please describe. I am unable to set the arrow circle color. Looking at the code this seems to be hardcoded to the color White.

Describe the solution you'd like I'd like an additional property to set this color.

Describe alternatives you've considered I considered making my own fork but for such a small change it is not worth the effort.
