DETAILS
Launcher: NeoLauncher (fdroid)
Wallpaper: Doodle live wallpaper app (fdroid)
Icons: Arcticons Icon Pack (fdroid)

If you’re like me and prefer a simple home screen but still use quite a few apps regularly, Neolauncher has a nice feature called cover mode where you can choose a single icon to represent a folder of icons. I don’t like the chaotic feel of the standard folder with several miniaturized apps smooshed together.
