Green is the same as red in sync mode but red is the same as track not selected in play preview mode %^$$#^^!!

You could have an option in the Plugin
Solo > left click ON - right click multiple ON - left click all OFF except current track.
(that is the way BB works)
or
Solo > left click ON - left click + ctrl all OFF
