Button Customization

Pippin – crazy stuff. Thanks !

Sorry I’m a noob – if I make changes in PHP regarding some of the button names (like ‘book’ instead of ‘purchase’) – then whenever the plugin will update – it’ll rewrite to old names (default that come with the plugin).

Is my understanding correct? Is there a workaround this?
