[Appointments+] ZAR currency

Every now and then I run into issues with ZAR currency not natively supported in WPMUDEV plugins.

The latest is Appointments+ Can this be added rather soon?

(I also advise something like a 'Terms and Conditions' with every plugin that stipulates clearly something like: "Don't use this plugin if you intend to ask money and you are in one of these countries where we don't support the currency yet [mention the countries]" This way a client will know not to bother before setting everything up."

It's just frustrating.
