At the moment there is information about interest earned since the beginning of the month, and interest earned since a pot has been opened.
As a minimum, I would like to see how much interest I’ve earned in the current tax year so I can avoid going over the tax-free limit (20% earners £1000, 40% earners £500).
On top of that, a tool to help not going over the tax-free limit, so I know how much to move to a Cash ISA for example.
