Hard to spot new activity in Chat list, slightly bolded font not enough to find
The chat list has a lot of data (chat channel name, avatar of user/users, last line typed, date/time, etc.) That is a lot of data and it all starts to blur together. Simply the thickness of the chat title/name is not sufficient to allow the user to quickly determine which chat has new activity.
1) add color in addition to bolding the chat title/name
2) add an option to allow the user to select a font color for the chat's with new activity in order to allow the user to adjust as necessary based on their color capacity (and make the method of finding this property easy - not a good track record to date on this one)
