Twitch App UI Redesign

Hello everyone,

This is my redesign of Twitch App which is an operator of online video gaming communities.
My topic is which function would be if there is a fourth button in the tab.

After the research I think it should be the "Go Live" btn, which is for the streamers who need to start broadcasting quickly and manage stream function, broadcast histories and so forth.

I hope you will like it :P
