In the account's row, click the button with the crossed-out eye icon and confirm with Hide. The account disappears from the Monitor list and is no longer counted in the summary cards at the top (Critical Balance, Low Balance and today's spend). To undo, click the Hidden button on the controls bar, find the account in the list and click Restore. The Monitor reloads, and the account shows up again. Note: the Monitor's hidden list is separate from the Account Center's hidden list, so hiding an account in one doesn't hide it in the other.
