Configurable glyphs for barcode and mobile check buttons
Allow libraries to select different glyphs to use next to the barcode and mobile check features.
For instance, for the library card, instead of a credit card (https://fontawesome.com/icons/credit-card?f=classic&s=light), an id card (https://fontawesome.com/icons/id-card?f=classic&s=light). For the mobile checkout, instead of a shopping cart (https://fontawesome.com/icons/cart-shopping?f=classic&s=light), a barcode (https://fontawesome.com/icons/rectangle-barcode?f=classic&s=light).
This would allow libraries to maintain branding currently in place and provide continuity across different web properties.

Continuity with branding is very important, I agree with Kara, please add these features to allow for library control.
