Can‘t edit border color and cricles color separately

Hi,you made a great plugin!! It helps me create the timeline I wanted.

When I edit my timeline,I found a small flaw:The cricles color does not appear to be edited separately from the border color ?

So I can’t have a wanted cricles color without changing the border color.

Can you add a control to edit the border or cricles color separately?

Thanks!!

Have a good day~
