Search currencies by common names

[kirillt]

Currently, the only method to add a currency is by entering its exact three-letter code.

From a UX standpoint, this is suboptimal because:

• Users may not always know the code.
• The sequence of letters in the code can be easily confused.

Optimizing the process to allow currency addition by their colloquial name would greatly enhance the experience:

• USD — dollar
• RUB — ruble
• KRW — won
• KZT — tenge

Additionally, incorporating typo tolerance and localized input can significantly boost usability.

Search by country should be implemented, too.
