Hi, simple suggestion.
In the context of Stocks ISA, there should be a view that lists all assets and their present value. Currently the closest is the “pies” view, but that doesn’t list cash (or “free funds”).
This is conceptually extremely simple: one table where each row is an asset (tradable securities, cash, and possibly items) and containing at least one column named “market value”. For example 1000 pounds would have value of 1000 pounds and 200 shares of VUSA would have market price per share time number of shares value.
