Scrolling doesn't work
Right now you are only able to scroll through Twitch-Chat by using your Mouse Scroll Wheel. When you are on a Laptop that uses a Touch Mouse, you scroll by clicking the (too tiny) scroll bar to the right of Chat. When doing this, new Messages will bug your current position lower. So basically the Scroll Wheel is totally useless when using the Drag and Drop Scroll Wheel because new Messages make it impossible to read what you wanna read. I don't understand how this isn't fixed yet.

this still isnt fixed.. what a shame.
there seems to be a new scroll bug now which randomly scrolls down your followed channels to the bottom.
