I agree. It's time to listen to the millions of users who have voiced their concerns. How many times does this feedback need to be expressed before you restore the functionality that worked effectively on the desktop version? Removing features that were functioning well is unjustifiable. The layout should clearly follow: Estimate - Sales Order - Invoice. It’s illogical to use estimates as sales orders, and then rely on those estimates to quote items that may never be purchased. This approach needs to change.
