Have an item in your project that you're still working on? Need a reminder to come back to it later? Flagging those items can be a huge help.
1. Add a new item in the builder, or click an existing item to edit. In the overlay that appears, click the Flag check box.
2. You may also add any notes near the bottom of the overlay so that you can quickly view those in the builder later.
3. Click Save, and when the overlay closes, you will see the item with a flag next to it
Hovering your mouse over the flag will reveal the note that you created.
