More Customization - Sign Up Page & Offer

If we link directly to the offer we have zero ways of customizing "the cart" also I would like to have it not like they are setting up an account (even though it does) for the user to stay in the mindset of checking out. I just don't think it works well for a cold lead, so I still use ThriveCart.

Also, the Sign up pages, as so limited on what we can add, that I still build my pages inside WordPress, again as they are, they aren't that favorable for cold audience conversion IMO>
