Can the logins widget on the dashboard allow more than 12 months to be selected and displayed? The Admin > Setup > Logins report goes back until the beginning of time so surely the widget can match? Or overlay years together e.g. last 5 years with different coloured lines for each year Jan-Dec.
To see login patterns we need to be able to compare year on year, not just the last 12 months. That way we can see if peaks and troughs occur at the same time every year or are because of certain events.
