Install Stremio with Premiumize. There’s two main add-ons you need,most guides will point to them. From the top of my head it’s Torrentio and Cyberflix.
Sound TV for twitch.
Smart Tube Next for awesome ad free, sponsor free YouTube.
TiviMate for IP TV (like once eoff $30 app)
I like Dreamy for a screensaver.
Mouse toggle if you need a mouse and want to use the remote.
Xmanager for file management. I can’t remember why but it’s the only one that can open zip or something like that.
