When using
LOGICALDRIVES=active:1,interval:30,color:ffffff,row-text:%1: (%3),diskio:0,threshold1:7 90 0000FF,display:%8[1.1b]B free of %5[1.1b]B
the threshold does not turn the line red unless %7 is added to the display. Also when the line does change color the row-text color does not change with it.
