Unit memory and search in converter

I use converter on a frequent basis and I face 2 issues with it.

  1. There is no search function

With the growing list of currencies and the addition of crypto it is increasingly difficult to find the currency you want from the list

  1. It doesn’t remember the currency after app restart

Compounding the above issue is the fact that if the app ever suffers a restart, or the converter’s memory is reset, it forgets the selected currency

These two QoL features would go a long way to improve the usability of converter
Thanks
