Can Button Text Change?

Loving this plugin but I’m wondering if any of it can be customized outside of css. I have it connected to my shop and showing the ‘add to cart’ button, but when a product is out of stock the button says ‘Read more’. Is there a way to change the ‘read more’ text to say ‘sold out’ or something like that?

Also, would love the ability to draw the area for the hotspot (so it’s not just an icon) so maybe that can be a feature added at some point. Thanks!
