More radiant color for Solo
When we click on "Mute", the color change is a nice bright yellow. But when we click on "Solo" the color change is not as noticeable. Please make the activation of "Solo" the same bright yellow as "Mute". Perhaps even make it "Bold".
I have many times scratched my head wondering why a track can't be heard. Then I squint at "Solo" as see that it has been activated.
