Don't fix what isn't broken. There's no need to change our channel pages.
The new layout is cluttered and confusing, and will require viewers to click through multiple tabs and panels to find the information they need. Just leave the channel pages as they are and let us choose and design our own panels, extensions, and information that we want to show.
Panels and an Offline Screen used to show viewers all the information that ProLucius mentioned, all on one screen, without clicking through tabs. I don't see how splitting the offline screen into three or four tabs makes usability better - it now requires MORE work to see who I am, what I stream, and when I stream.
From a user perspective - not even as a streamer - I don't think this change had a net positive effect on usability.
just because something isnt broken, that doesnt mean it cant improve, sure the twitch page is fine, however i can be highly improved to make the new viewers who find you easier to know things about you, such as when you stream, what youre streams are about and what kind of person your streams are.
