Is there a way to show reminders which have passed? I use them for due dates but can't see them in Reminders section after the reminder has expired. A query string I could put in search, perhaps?
Reminders are also visible in Google Calendar (assuming you've switched away from Google Tasks).
The easiest way to see them is probably with the "Agenda" view.
(Unfortunately, Reminders don't seem to be searchable in the calendar at the moment.)
