When you're mentioned in a chat, this isn't a problem because the red icon helps. However, when there are chats in channels that you follow but you aren't specifically mentioned, you can BARELY notice the difference in boldness.... and my eyes aren't even that old yet! haha

So if you guys could improve that either by increasing the weight of the boldness or tweaking the color/shade of unread chats, that would be AMAZING. Thank you for your attention to this matter :)
