@Danilo Venom Actually NOT TRUE--had to create an account to correct your misinformed comment and set the record straight.
Chatsen most definitely DOES HAVE the feature to watch Twitch streams. So DO NOT BE MISLED by this above comment. CHATSEN offers the video feed directly inside the application just like Frosty does.
Please do not take this personally or do not take offense to my reply. I am aware that the stream player is not as easily visible as it is in Frosty or the native Twitch app player. So it is not as intuitively found and I can see how you might not understand where the button for also playing the video feed is located in the Chatsen UI.
So I will type out a little step by step guide to get the live stream to play with your streamer or choice. But I bet now that you know there actually is the feature to play the stream -- You probably will find it by just checking more thoroughly.
