I use Nova Prime Launcher, which has a feature that allows you to get rid of the Notification Bar at top, but only on the home screen. I like to keep my homescreen/desktop neat and clean. I have 5 Docks, and can put 7 items on each Dock. Right now, I have 20 folders on 3 Docks, leaving space for 15 more items on the remaining Docks. The Docks in Nova Prime are my favorite feature.
With the Edge Drawer feature, I really don't have any need for widgets on my S8 Plus. I have lots of widgets on my Note 4, which takes forever to load each time I restart. I want to keep my S8 Plus lean and as fast as possible .....
