Yes, I've used that avenue to send back feedback to the product developers multiple times expressing the same concerns and asking the same questions, as well as talk to a representative, since the new layout was enforced for all users of QBO. 

I've looked in the settings to personalize the sales forms as well, but the options given that we can change will not benefit me or other users with this problem. 

In conclusion, your statement, "your satisfaction is essential as we navigate these changes together", seems very disingenuous considering all of the negative feedback that has been given by the distinctly large number of users-- with zero efforts on QB's end to remedy the problem. It's incredibly frustrating to look at these numerous posts stating the same thing: "Please give us the option to switch to the old layout/format for estimates & invoices because of reasons A,B,C, etc." To see every response from QB: "Please submit your feedback directly to the product engineers and they MAY consider your feedback."

The point of product engineers to better a product that makes the customer happier with said product. Considering the large number of users that have replied on this thread stating they're going to switch to another bookkeeping/accounting software due to this update, I'd say the product engineers missed the mark by a mile.
