Smooth scrolling chat bar (rather than jumpy)
There should be an option on twitch where you can have the chat sidebar smoothly scroll up, rather than move up immediately each time a new message is sent. The current view makes it so hard to follow along, as you have to constantly flick your eyes upward in some of the more quick moving streams.
The new option could speed up/slow down based on how much comment traffic is going on at the moment. Seems like a very easy idea for twitch to implement
