Smart Lists are much like ’saved searches’ that allow you to create lists out of your search criteria. For example, you could create a Smart List that lists all the tasks from a particular list that are due in the next 3 days and are tagged with the tag bill.
To create such a Smart list, follow these instructions:
1. Tap on the Search button on the top left corner
2. Tap on the Calendar button
3. Tap on ’Dynamic’ as we want a dynamic date range (instead of a fixed from and to date range).
4. Select 3 Days and tap Done.
5. Tap on the {+} button to save this permanently as a Smart List
6. Finally, tap and hold on the newly created list (which will be created with the keyword ’*’) and tap ’Edit’ to rename it to Next 3 Days.
