The Lanes icon now is blue if it’s open, but we see with eyes that lanes are open when they are open. I think we don’t need additional indication that lanes are open.
So the blue color could be in icon only if there are more than one lane. Like it is in Inspector - blue icon in Send section, green icon in EQ section etc. And those colors came in only if there are changes, not when sections are open.
Or, if you leave current blue when lanes are open, then there could be light blue or green (like Inspector’s EQ section) if there are more than one lane.
And… if there will be green color in icon, then there won’t be a need of striped event for track if there are more than one lane. These stripes are annoying.
