Lawnchair. Get it? It's a bad pun, we know. Based on Launcher3 from AOSP, Lawnchair has all the features of the Pixel Launcher (including the Google Feed), plus customizability. Best of all? No root required.
Notification dots and improved shortcut UI have been backported for anyone to use! Perfect for anyone who won't be getting Android Oreo anytime soon.
Icon size, label, rows, and columns are all adjustable. Lawnchair also supports icon packs, and the Pill is customizable as well. These aren't the only features, and more are added regularly.
If you have an issue with Lawnchair, we're more than happy to help. Ask around in our Telegram Group, G+ community, or mention us on Twitter. Follow us on Twitter for announcements as well.
