You can add an Action Date to Items. When you add an Action Date to an Item, a reminder will pop up when you open Paper Tiger. In addition, you can click on the Reminders tab anytime to see the Items in the Reminders section based on your Reminders Horizon.
The Reminder pop up will occur based on the Reminders Horizon you have set up in your Preferences. So if your Reminders Horizon is set for 7 days, the Reminder will pop up 7 days prior to each action date that you've set for individual Items or for the Review Frequency for each individual Location.
To view and edit the Reminders Horizon for your Locations, click on View at the top menu, then drag down to Preferences.
