If you don't want to see the 'All Transactions' row at the top of the account list, you can remove it: tap on the pen above the account list and choose the card 'All transactions' > tap on 'Delete'.
If you group your accounts by themes – for example, personal accounts and business accounts – you will see the total sums of each account group in the account overview.
Tip: If you prefer to have the unread transactions at the top of the account list instead of 'All Transactions', you can add the card 'Unread' as follows: tap on the pen above the account list > 'New Card' > choose 'Unread'.
