🎉 1.1.0 Major Update
1. Japanese Yen "円" Support 🇯🇵
More Japanese Yen formats can now be identified and converted:

¥1000 - Yen symbol precedes the amount.

円1000 - Japanese character "円" precedes the amount.

1000円 - Japanese character "円" follows the amount (common format on Japanese websites).

Supports thousands separators and spaces: ¥ 10,000.

2. Smart Hint Function for '$' Symbol 💡
For simple $ symbols (e.g., $50 on a Taiwanese website), the extension will no longer automatically assume USD. Instead:

Hovering the mouse over it displays an aesthetically pleasing floating hint window.

The window simultaneously shows the conversion results for "Assumed as USD" and "Assumed as TWD".

This allows you to judge the actual currency yourself.

This function can be toggled on/off in the settings.
