We operate in Australia and by default when we select Australian Dollars it is listed as $AU but here in Australia we just want to have this listed as $ since we don't deal with international markets. At the moment we use the USD currency to have the $ displayed correctly. It would be nice if you were not so US centric but changed the display of the currency based perhaps on the location that you select as a default. Here $ infers that you are talking in Australian dollars, $USD infers you are talking about United States Dollars.

For the life of me I cannot work out how to remove the "AU" reference from my pricing table, see here: https://prnt.sc/14frmu1
