i never used Nova Launcher before either till my note 4. i have my note 3 for a while and loved it and was debating on a nexus 6 or note 4 but i like some of samsungs features so got the note 4 gear s combo last week. but i wanted a new feel i was tired of the samsung icons and it didnt feel like a new phone so i downloaded nova along with a lollipop theme and git material wallpapers and the majority of the lollipop icons to make the phone feel diff.
i personally like a clean homescreen besides the dock icons and i put all my stuff on my left or right desktop but keep home nice and clean. here are 2 of my screens home first then my right one with my main use aps.
again this is nova launcher on my GALAXY NOTE 4. i tried the go launcher and did not like it. you cant use you own widgets and loading the app tray was way to slow and laggy for me. Nova is beautiful very customizable and smooth.
this is my screen to the right of my home screen, i like a clean home screen.
