Quick view of the task in calendar, map and lists
A task summary in a popover or sheet: the key block on one line, the charge, the stage action and a way into the full task.
The same summary everywhere
- The key block on one line: “Today 18:00 · Room 2”, or the address and time slot.
- Charge: visible to whoever manages the business.
- Action at hand: move the stage forward from the summary.
