I don't think this is very useful. You mentioned two links which are already there. What links do you not see that you would want to add? Because if you don't want to chat, just... don't click that link.
In addition, it could actually be detrimental because:
- It may introduce new bugs
- It may be confusing
- It will cause more confusion when people report bugs / ask questions. Now we have to ask what everyone has their top bar configured like.
- It takes the team's time from building more important features.
Plus, your feature-request doesn't have any freehand circles. I could be convinced to upvote this if your post had a clear example of why this is needed, with a freehand circle around it.
