Nova launcher was used by me from 2 yrs it is the best .actually I try many custom roms and some of them has very different way of apps configuration . so, I use this launcher always.
And truely this is the best launcher which had not stuck even once till now . the app search , gestures, settings are awesome . I even use nova setup till now . it gives all the variant of themes . you can only see that 99% from 100 of iconpacks support or shows compatibility with nova launcher. Thousands of themes are customizable a put in nova . it also has fast output rate in searching and accesing the apps. It also has feature of swipe to an app to open different app. And their is no end to it . the newer or latest version of nova launcher also supports google now and gives latest news with new upcoming updates. Google assistant also works in phone which has android version above marshmallow .
My nova launcher was with the dark theme before .
But now I had configured it to normal design and settings for easy use .
THIS IS MY SETUP
