Hi all! I know this doesn't solve all of the requests here, but I wanted to let those of you intereseted in a more formal/simplistic template know that we've just released one that can be chosen as the first step when creating a quote! The new template is called "Basic" and the old one is "Original". This is the first step for us to make Quotes even better for you in the long run. Thanks as always for the feedback!
