yea thanks central music but reading the manual doesn't tell me (p. 706 & 707) how to change brightness or colour of the automation lines by default. it tells me how to change colours of the selected tracks manually or by default but i'm not sure if that helps me here. Even if I could change it manually I wouldn't want to do it all the time for each track. Maybe (and hopefully) i'm mistaken.
all i'd hope is brighter colours for automation lines so i don't have to zoom all the time to see which track contains what information.
