If you could make a secondary date field visible on the calendar view’s sidebar it would make it a lot easier to use the drag and drop scheduling features. Even the example on the calendar view guide would need this functionality: https://support.airtable.com/hc/en-us/articles/216945218-Guide-to-calendar-view
In this example there’s a “Date/Time Scheduled” field and a “Due Date” field. If you use the “Date/Time Scheduled” field for the calendar view, you’re not able to see the “Due Date” field in order to decide how to schedule your week.
