I’m assuming the “Selected Channel Brightness” is the feature that changes the brightness of the “white” color for selected tracks. It doesn’t seem to work on my end but maybe that’s a bug. It still appears as “white” when selected. I’ll assume it’s a bug.
I have seen it. I just wouldn’t put too much hope in it. There are quite a few unresolved UI issues (not just graphical ones) that have been reported over the last decade(s), but we rarely see any intention to revise them.
Fair enough. I suspect the reason is partly due to a lack of imagination the part of the users. They don’t know that improved usability would impact them positively. Also, I’m partly doing this for the sake of research.
