I have an idea for the app. I find it annoying that in the overview page, all my stocks are in GBP even the US ones. Then when I go into say a US stock, the price is in USD but my holdings are still in GBP. I think it would be nice if it was all in one currency. So maybe the user picks which currency they prefer or maybe the US stocks show all details in USD and UK stocks show all their info in GBP. Or the stock price for a US stock could still be in USD but in brackets beside it could the the price in GBP. For example: TSLA = $661.75 (£480.74).
I hope this makes sense.
What does everybody else think?
