Re: Styling for "Payment instructions"
For anyone reading this thread later, upgrading to 184.108.40.206 has added the ability to style the payment instructions as I was looking to do.
As I skipped several points (I think I went from 220.127.116.11), I'm not sure exactly which update added this feature, though.
Currently transitioning to X-Cart 5.4.x.x. Oh the joy
