Click on the clock icon in the main menu and then on Options due dates.
The number in the red circle indicates the number of due dates coming or past, and if there are none, no number will appear.
The list opens sorted by Expiration date field, filtered to show only the options expired or expiring in the next 24 hours.
The expiration date is colored in red if already past, in orange if coming, and in black otherwise.
Remove the filter on the expiration by choosing Show all in the options at the top, or put it back by selecting Expired and Expiring in the next 24 hours (default option.)
To remove a row from this list and its relative notice, the affected quotation must be confirmed or closed, or the option removed. Click on the blue arrow beside the number, or double click on the row, to open the quotation.
