What do you want to be added or improved?

As a user I want to see e.g. "£" instead of "GBP" consistently across the UI (except when picking a currency, where the symbol and the name could be shown, for clarity).

This would also ensure a consistent display, as in the UI there is a mixture of GBP 1.00, 1.00 GBP and 1.00 British Pound formats

Why do you need it?

• save precious real estate in widgets
• use a more familiar identifier of currency (in every day use, it's uncommon to use currency names such as GBP, USD, TRY etc)
• consistent formatting of currency makes it easier to read

How do you imagine it?

Anywhere the currency name is used, the symbol would be used instead. E.g instead of GBP -100.99, show -£100.99

In the large widget, the header would show -£100.99

The minus symbol prefix matches Excel's default style.

I think it could be worth discussing making it the default, too.

I'm a developer with a bit of Kotlin experience (not Android though). I'd be interested in making this change, if there is interest.

And thanks for the app! It's awesome, exactly what I was looking for :)
