Currently we have 3 colors/styles for showing a channel name in the tab bar:

• (1) Normal: a faded white/grey
• (2) NewMsg: a pink-ish color, used when a channel gets new messages
• (3) Highlight: bold red, used when a channel has a mention to the user

These are listed form the lowest priority to highest. For example if a channel is shown as (2) and a new message to the user is sent we show it as (3). After that new messages don't turn it back to (2). We reset the state to (1) when the channel gets focus.

I suggest we insert this for (2) and shift (2) and (3):

• (2) JoinOrLeave: yellow, used when channel has join/part/quit activity.
