Bug Reports
#1

whenever I update
color of track of custom apple script slider widget, by
tell application "BetterTouchTool"
update_trigger "UUID" json "{"BTTTriggerConfig":{"BTTTouchBarButtonColor" : "4.0, 204.0, 255.0, 255.000000"}}"
end tell

color won't change when I FIRST-TIME trigger the command, but only freezes custom apple script slider widget
