Can I show only the currency code instead of the full currency name?

Currency Converter+ can display a full currency name or the currency code in the drop-down chooser currencies over the prices. By default, on some installations, the drop-down chooser will display the full currency name consisting of the currency name and the currency code.

However, it is possible to change the default behaviour to display only the currency code. 

In the Visual styles, select the Drop-down chooser section:

Then go to the Currency label style feature and just check the option labeled as 'Only currency code':

After that, the currency chooser on the prices will display the currency code instead of the currency name.

If you have configured a menu button, you can also display full currency name or the currency code in the drop-down chooser of the menu button.

To do so, back to the Visual styles main menu and look for the section called Menu button:

Once there, you can check, in the Currency label style, the option labeled as "Only currency code".

In the screenshot below, you can see the menu button when the "Only currency code" option is checked:
