I liked my home screen being in the middle as well (like on Note 2) I found you 'can' change it on the Note 4......long press on a blank spot on your home screen and when the ghost like screens come up, long press again on the screen you want to move and drag it in the position to the left or right and release.Disabled it because I wanted the space back, then realized that turning it off made that whole screen disappear. It doesn't take up a home screen; it exists to the left of all the home screens. I enabled all 7 home screens and turned Flipboard back on. I'd still prefer the primary home screen be in the center, not left, but I can live with that. (Unless someone knows a way to change that setting?)
Disabling it was the first thing I did.
I am in the process of making my Note 4 self aware.
