Lawnchair v2

The official Google Pixel launcher comes with a ton of useful and interesting features, but they are mostly relegated to the official Google Pixel phones, and a few others. It turns out that the community actually loves the official launcher, so they built a customizable version that offers pretty much the same functionality.
Lawnchair v2 offers a large variety of options, some of which are not available even in the vanilla version. Users can change transparency, the themes, the icon set, and even the dock.
Furthermore, it's also possible to customize the widgets and the app drawer. It's worth noting that user can also back up their current configuration and experience with changes at will.
