A dot marks a day the store showed a different number. Between them the line carries the last one forward: we read every listing up to 2 times a day and record a point only when something moves. History beyond ninety days is in the app.

  • Run its own code on the pages it can access scripting
  • Act on the current tab, but only after you click it activeTab
  • Schedule work to run later alarms
