Remind me about this task: a pop-up for a deadline
Remind me about this task in Task List by Zaweba makes a linked reminder at the due time, and Task done on the pop-up ticks the task off.

A due date on a task tells you when something should happen, but only if you look. Remind me about this task, in Task List by Zaweba, adds a nudge that comes to you. From a task's menu or its editor, it makes a reminder linked to that task: by default a one-off at the task's due date and time, or, for a recurring task, following the task's own repeat. When the pop-up appears, its Task done button ticks the task without opening the main window.
It is the bridge between the two halves of the app, tasks you do and reminders that tell you when.
Setting it up
Open the task you want to be reminded about, or open its menu in the list, and choose Remind me about this task. Task List creates a reminder that points at the task. If the task has a due date and time, the reminder is set for then. If the task repeats, the reminder can take the same repeat, so the nudge comes round with each new copy.
The new reminder is a full reminder like any other, so you can adjust it. Change the time to give yourself a head start, switch the email on or off, or turn the sound on for something you must not miss.
What the pop-up does
At the set time a card appears in the bottom-right corner of the screen. It does not take the focus, so it will not steal keystrokes if you are typing. It plays the Windows calendar chime and offers Task done and Snooze.
Task done ticks the linked task, which moves it to Completed with the time and, for a recurring task, creates the next one. Snooze offers 10 minutes, 1 hour, Tomorrow or a custom time, for when the moment is wrong.
If you have set up email in Settings, the reminder can also send an email through your own mail account.
When it earns its place
Not every task needs one. A list with a reminder on every row quickly becomes noise. Save it for deadlines that matter on the day: a form that must be posted before the last collection, a call booked for a set time, a payment due by midnight. The due date shows in the list, and the reminder makes sure you look at the right moment.
It also helps when you will be away from the list. If you spend the afternoon in another program, the pop-up finds you.
Keeping Task List running
A reminder can only pop up while Task List is running. Closing the window leaves it in the notification area, and File, then Exit is the only thing that quits it. Starting with Windows, which is offered the first time you open the app, means it is always there. If the PC was off when a reminder was due, it fires once at the next start, marked late, and the reminder history records that.
Reminders and the daily summary
The optional daily summary email lists today's tasks, overdue tasks and the day's reminders at a time you choose, 07:30 by default. Linked reminders show up there too, so you see the day's deadlines over breakfast and get the pop-up when each one arrives.
A word on duplicates
Because the reminder is linked, there is no need to create a separate reminder with the same title. One task, one linked reminder, and ticking either side keeps them in step.
