Show current editor document indicator in Binder... doesn't work well.

Options -> Appearance -> Binder -> Checkbox “Show current editor document indicator in Binder”

When using darker colors (Green, red, brown) for the binder background:

Unchecked, the Binder shows some difference between the background color and the highlighted line.

Checked, the Binder shows LESS difference between the background color and the highlighted line.

No matter what darker color I set the Binder background to, the color difference is difficult to see at a glance. For some colors, the difference is nearly nonexistent.

I’d really like to be able to SET that color, because the algorithm’s choice is not adequate.
