Been searching for some useful chrome plugins for twitchtv lately, thought I'd share.

Twitch Live - Displayes the online status of the twitch channels you subscribed to in the top right corner of the browser

TwitchTV popout plus - hides the twitch player bar in popout windows and makes it fade in when you hover the window

Better TwitchTV - bunch of "improvements" such as site dimming, chat options

Hope it will be of use for someone.
