Throughout the extension it refers to the term 'Orders' but in the hikashop main menu system it calls it 'Sales' which is quite confusing. I think it should be named 'Orders' instead so it is consistent throughout and also that is the common term used in shopping carts.
It is called Orders in the backend joomla menu as well.
(I realise i can override this term, but this is a suggestion to update the core extension )
