Follow-ups and the calendar
A real calendar, not a list of overdue reminders.
Follow-ups have a time and a duration and sit on a month or week grid. Drag one to move it, drag its edge to change how long it takes. The backlog rail holds anything without a date; drag it onto the grid to schedule it.
Arrow keys move a selected follow-up by a day, which is faster than dragging when you are rescheduling several.
You can subscribe to your calendar from Settings → Profile to see follow-ups in the calendar you already use, and separately connect a read-only calendar address so Lyncera can prepare the people you are about to meet.
