When seller hub originally launched, I was of a similar opinion to you and the OP, gave up on it after about 5

minutes and switched back to classic view.  However curiosity got the better of me, and while continuing to use classic view, I spent a few extra minutes, over a couple of weeks, playing with Seller Hub, and after finding how simple it is to use I switched back permanently to the seller hub and have used it ever since.
