Another great feature in iOS9 (and adopted by iThoughts) is 'Remind Me'. This will add a reminder linking back to the current map in iThoughts.
In the following video you can see:
- I open a map
- I long press the Home button to launch Siri
- I say 'Remind Me About This' and Siri creates a Reminder entry linking to the current map.
- I close iThoughts and open the Reminders app.
- I tap on the recently created reminder and it launches iThoughts with the appropriate map.
