This question is an exact duplicate of:
Since Show inbox updates in the page title hasn't been picked up, I propose a different use of the page title.
Whenever "something" is updated on a question, the title should reflect the number of changes or at least that changes exist.
My motivation behind it is that I'm interested in the question itself when I browse SE. I want to keep the tab open and see if there are updates to the question without opening the tab.
It should be easy to implement since the updates are already coming in.
Proposed updates that should be counted:
- Edit to question
- New answer
- Edit to an answer
- (if there are no answers yet, number of new comments)
