Hi! NVIDIA Shield TV Pro user here, but I don't know if this really matters. I was wondering if it's possible to have multiple custom app rows on the home screen without using external launchers. I could always use the favorite apps one for everything but at least I want to separate games from streaming services. Any help?
Nebula Manager, a simple app with the sole purpose of adding another Apps' row to AndroidTV home screen, it's just adding another single channel row on the home screen, and lets you select mobile apps that don't have the default rectangle shape app-icon to populate NebulaManager's channel row. The app wasn't compatible with Android 11+ till about a month ago, and has been updated to be compatible up-to Android 12 now; but I don't know if the ShieldTV will automatically download the latest version at the moment. If you cannot find the latest version in the PlayStore, which I think is 1.50; you can find the APK download on Apkmirror website to sideload. I haven't tested the latest version of NebulaManager, but the app used to work perfectly with AndroidTV 8/9/10 devices.
