The Task Editor
The full editing sheet, field by field. Dates and durations, repeats, alerts, locations, priorities, tags, and lists.
Quick entry covers most days, but sometimes a task needs the works: a repeat rule, an alert offset, a location. The task editor is the full sheet, and this page walks it field by field. Which fields you see depends on what kind of thing you're editing; the differences are called out below.
Opening it
Swipe left on any task and tap Edit, choose Edit from the long-press menu (right-click on Mac), or tap the info button while editing inline. On iPhone and iPad it opens as a sheet; on Mac it gets its own window.
Title and notes
The title is plain text. The notes field understands markdown: headings, lists, links, and bold render formatted when you're not editing, and switch to plain text while you type.
Dates, times, and durations
Set or clear the date, add a time, and give timed items a duration so they claim real space on the Timeline. Calendar events add an All-day toggle, and all-day events can stretch across multiple days. When you have World Clocks set up, the globe next to the time picker schedules in another city's timezone; see World Clock.
Repeat (reminders)
Repeating is a reminders feature, because reminders live in Apple's reminder system that's built for it. Choose daily, weekly, monthly, or yearly; set an interval like every 2 weeks; pick specific weekdays or days of the month (including "last day"); and end the repeat never, on a date, or after a count. A repeat needs a due date, so turning it on brings the date along.
If you're tempted to make a simple task repeat: something you do for consistency is probably a habit; something with real deadlines is a repeating reminder.
Alerts (reminders)
With a due time set, choose when the alert fires: at the time, or 5, 10, 15, 30 minutes, 1 hour, 2 hours, or a day before. Timed simple tasks notify at their time automatically, no configuration needed.
Location (events)
Calendar events get a searchable location field, like Apple Calendar's: type a business or address, pick from the suggestions, and the event gets a proper map pin. Free-typed text saves as a plain label too.
Priority (reminders)
Reminders carry Apple's None, Low, Medium, or High priority, which also shows in the Reminders app.
Lists, calendars, and tags
Simple tasks can be assigned to one of your lists and carry color-coded tags. Reminders choose their reminder list, and events choose their calendar, each grouped by account. Tags belong to Finalist's own items; reminders and events don't have them.
More details (events)
The More Details button hands an event to Apple's full event editor for invitees and everything else (on Mac it opens Calendar.app). Same event, deeper controls.
Deleting
Delete lives at the bottom (in the toolbar on Mac). Deleted simple tasks go to the Deleted list, which appears in the Lists tab whenever it has something in it, and can be restored from there. Reminders and events are removed from Apple's apps directly, so those deletions are for keeps.
One more trick that lives outside the editor: the long-press menu's Convert submenu turns a task into a reminder or an event (and back), carrying its details over.
