You can create an item simply by typing into the day plan or assignment field.
Use the @ sign to tag/assign a teammate to the item, and use hashtags to specify priority or item type.
To mark any item complete, click the circle icon next to the item from any view.
Note: Once you mark an item on your day plan complete, it will be hidden by default. To see completed day plan items, change the day plan filter settings to show completed items.
