A:Answer The question really is does Chromecast let you add additional apps/channels to it, Nope. It is not like a roku or smart TV that has a built in menu of apps. I prefer roku or smart TV, i don't want to cast everything, heck my phone needs to charge or I need it for doing something else. I leave someone else needs to cast. I could use a laptop but it needs to sit somewhere and then I want a mouse. Yes a tablet would be better if it can be dedicated for use with the TV only.
