I like the icon for the app folders in the google now launcher which can be seen on the Nexus 5. Basically when you group apps together on the home page the icon is round with an overlay of the apps in the folder. I find this much better than how Sense uses a square icon that shows small icons of the first four apps in the folder. Is there any way I can incorporate this into my M8? Can I do it without switching launchers or rooting?
