Right now I can have the text be uppercase when adding a text box to a product, however the Custom Text module doesn't seem to support this. It has all the other options in the back-end like scale, rotate, max font size, etc. Any way of forcing this text to be uppercase? I tried the font hack from this thread (https://support.fancyproductdesigner.com/support/discussions/topics/13000018955) but it isn't working when I try it.
If you've only got one font then you could add some custom css to the text input. But obvs won't work if you allow the customer to change font.
Feel free to add as a feature request!
