Though the most used laincher in play store the google now launcher seriouslu lacks features. It does not support icon packs and no customization is possible in it. It neither recreates the full stock android look neither it has customizable options. It just has that one feature of google cards and thats all. It is also a heavy app and needs updated google stuff to work correctly. In place of Google Now Launcher , launchers like NOVA, EEVIE or ACTION LAUNCHER are much superior. Even the Pixel Launcher is much better of a pick in Android Nougat.
