I am so with you.  No, Feedback DOES NOTHING.  I've wasted more time and energy on the stupid changes and implementations they've made and putting forth feedback, only to get nada.  It's so sickening.  I'm making changes to wean myself off of QB because it doesn't serve me as I need it to any longer.  But I need to get up to speed on how I'm going to handle everything without the accounting software and keep working (one person show).  I don't have a big business, but I need it to work for me, and I just can't navigate this with confidence any longer.  And they've wrecked my invoices.
