Adding images to Group Chats or Channels

The ability to change the image of a chat or channel in the navigation panel. In chats it is nice the individuals’ photos are there to differentiate on a quick look and that functionality would be great for group chats and channels as well. This would specifically be useful when not text searching for a specific channel or using the pinned chats and channels. Even if it were just being able to define a chat or channel with a color that would make navigation easier.
