This is a fantastic suggestion. I just want to piggy back off it & also add that I would also love to be able to easily distinguish pending transactions from settled transactions. Some banks choose to have a separate section in the transaction view, that lists still pending transactions. I don’t mind that but I don’t think it’s necessary to have that always visible, it seems like a bit of a waste of screen real estate, when you’d prefer to only have pertinent information visible.
My suggestion would be to have the pending transactions just listed within the transaction view as per usual but have them highlighted or bold or have a box around them or something. What would be ideal, at some point in the future, would be to have search/filter options, and one of those options could be to only show pending transactions.
The running total along the side is a fantastic suggestion for now. All these features come together to help the end user easily verify their transactions, see if they’ve been overcharged or if the transactions and the available balance don’t add up etc.
