Many times while I am viewing streams, I like to check in on several of the people I am following. I would love to be able to scroll from room to room without having to go back into my Following list. If there were possible to have simple < and > indicators on either side of the screen that cycle you to the next active stream on the list, that would be very helpful. Could also help when browsing for new streams. For instance, in the "Up and Coming" or "Top Streams" category, a person could more easily visit more streams and find people to support who they like.
Also, I have very little confidence this is in the proper category. :)
