With design inspiration from Chainfire's Sideload Launcher for Android TV I present to you Simple TV Launcher for your Google TV. (And any other Android powered device including Android TV!)

All your apps upfront, simple, and lightweight. Easily navigate to any of your apps by simply using the arrow keys. (On your remote, keyboard or game controller.) To get details or uninstall an app simply hold down on the app. To change the wallpaper, access system settings, or hide apps simply navigate to the bottom right to the menu icon. To access recent apps navigate to the bottom left and hold down to access the system's recent app menu. (Recent app menu not available on Android TV. Lollipop and up devices can only access the system's recent app menu.)
