1. Has a feature similar to the iPhone's 'reachability' feature.
2. A way to scroll up to the top of a feed quickly like the iPhone does by tapping the status bar.
3. A way to turn the keyboard into a trackpad like 3D touch does on the iPhone.
I am willing to live without number 3 and maybe number 2, but reachability feature is a must as I use it all the time. I also do not want to root the phone.
