I'm using a dark theme, and I have recently enabled the moodbar feature. I really like it, but the position indicator is nearly impossible to see. I don't know if this is because I'm using a dark theme on my desktop (I'm using Linux with XFCE wm). Here's a screenshot:

Is there any way to change the color of the position indicator to something more eye-catching?

@Gustavo-L-Conte Customizable color would be amazing if possible. Width would be useful, too.
