Planner
You have forty open tasks, six meetings this week and about thirty focus hours to do it in. The Planner lays your estimated tasks out against your working hours and your calendars, so you can see on one screen what fits, what does not, and which day each task lands on. It writes nothing to your board until you decide to change something yourself.
The Planner covers three things. The planning grid lays a day, a week or a longer span out hour by hour. Saved plans keep a schedule so you can compare it with the next one. Calendar feeds bring your meetings in from Google, Outlook or Apple, so the plan keeps clear of them.
The full chapter, with every step and setting, is in the app: open your account menu and select User manual.
