Ahh got ya. Use the search and then read as much as you want. For example
I have a Shield Pro but have never bothered with a launcher as I have mine set to open TiVimate as soon as the Shield starts. So I’m rarely on the home screen and rarely see it. If I want to use any installed apps I long press on the Hamburger button on my remote and TiViMate closes and my apps open up and I choose what I want to use like X-plore. Hopefully the above link gets you started. Have a great weekend.
