Ability to set other currency in Store settings (example, SGD, PHP, etc.). Or just put the currencies of all countries on the selection list.

Allow webmaster / creator to set other currency for the Store Settings. For example, SGD, PHP, THB, etc.

Alternatively, just show the currencies of different countries on the selection list so users can select depending on their need. It makes no sense to limit the list if you want people globally using your platform  who sells in their local currency.
