Channel ignore option

Since twitch does not have a reason to ban some streamers (e.g. cleavage drama streams), I still have to see them all the time and i get annoyed just having to see their thumbnail while scrolling trough the channels. So, I thought that maybe others feel this way to and bttv could have an option to be able to ignore streamers, so they wont pop-up ever.
