I know that Google Now Launcher was discontinued earlier this year, but I went to the Play Store and there was an option to enable it, and I did, just out of curiosity. I'm using nova launcher, and now there is an option to import data from google now launcher stub. I'm not sure if it was there previously, or if it's new. There is not an option to use google now launcher as the home app. Should worry about disabling it, or is it fine?
