Nova Launcher is the prime example of the level of customization Android can offer. The most popular Android launcher by far, it started out simply as a stock Android launcher with some extra features. Throughout the years, Nova Launcher has been just that but the "extra" features have just grown two folds, maybe more. The recent Nova Launcher updates have been about bringing the launcher features from the Pixel 2 to every other Android device. For instance, the last update added the Google search widget to Nova Launcher dock, below the icons. Exactly how it is on the Google Pixel 2 launcher. With a new update, however, TeslaCoil is expanding on it and allowing users to add any widget in place of it. After all, that's what Nova Launcher does best. It takes stock Android launcher features and expands on them. But since the expanded dock wasn't meant for anything other than the Google search widget, it only has space for a 4x1 widget. Which is fine really because a 4x2 or 4x3 widget is not something you'd want in the dock. Unlike the Pixel 2 launcher, search widget in the dock is optional on Nova Launcher. But if you want to add any other widget, you will first need to enable it. Also read: Which Android Launcher is Best for You?
