Pixel Launcher Released for All Android Devices in the Play Market

Amir Zaidi is a developer that released in the official Play Market the Rootless Launcher based on Launcher3. 
Rootless Launcher is a complete copy of the Pixel Launcher with several additional features. There is support for third-party icon sets, theme customization, you can turn on recommended applications and other options.

The developer used to call this launcher Rootless Pixel Launcher, but because of the Google policy that does not allow third-parties to use a company's trademark, they had to rename it. For the same reason, the launcher has no access to Google Feed that can be triggered with the swipe on the left on Pixel Smartphones. But, you can fix that after the install.
You can get Rootless Launcher from the Play Store, the source code is open and available in GitHub as well.
