I see a purple or mint coloured line on the side of my documents and transactions. What is the meaning of that line?

The coloured line indicates the to-do-status of your document or transaction.

• A white line says you haven't checked the item yet.
• A lavender line says you have reviewed the item but there's still some work to do. It's an item in progress which is still on your to-do list or can return to your to-do list. (E.g. you have snoozed the item because your waiting for a payment). After the snooze period, the item reappears on your to-do list.
• A mint line says you have completely reviewed the item and it's not on your to-do list anymore.
