It would be nice to have the ability to choose whether a connected account’s balance should be included in your total net worth figure. Perhaps just a tick box in the “Manage Accounts” screen.
For example, I have a separate “Bills” current account that I use to transfer the exact amount I need to cover my bills for the month when I get paid.
I don’t view this money as if it’s my own, so to remove that balance from the total net worth would allow me to easily see how much there is between all my other accounts at a glance, and ensure my bills can be set up properly in the bills section and see transaction history, etc.
