I have some general suggestions for a better channel rack:
1. Show bars (as explained in this topic)
2. Improve contrast of steps: Recolour groups of steps (their colour/contrast difference is too little for most of the people)
3. Improve appearence. This one is more subjective, but what it shows (improvements) are the name of the plugin + the custom name of the channel, performance monitors and bigger buttons for ease of selection, as shown in this reddit post.
