The default launcher works, pretty good in fact. But it would be nice to have more features such as double tap to sleep or more customization settings.
I know alternative launchers exist, but they never work perfectly. I was using lawncher but for some reason it works very bad recently (constant freezes ect...). And everytime i've tried a new launcher i found it less stable than default one. Therefore, more features on the default GOS launcher would be a great solution.
