Great feature, poor execution

Hi, I don't know why I can't upload the pictures, so i'll just write it down. You have a good feature for cathegories, but right now it's not efficient. People don't use it often, because of the how brain works. Chat can only be on the left side of the screen, or in the middle. But the left side is already occupied by the main interface. So, when you pick a cathegory, chat should slide from underneath the left interface to the center, at the same time cathegories move to the right.
 The great example is Opera's built-in interface for social media platforms.
Thanks.
