On the confluence wiki, the somewhat weird scissors icon is used as favicon for each page. When I've had a page open for a while, and someone updates the page, a notification appears in the bottom right of the page suggesting I refresh the page to see the update(s). When that happens, is it possible the favicon could be updated to show that the page was updated?

In the rare cases when I have so few tabs I can see anything more than the icon (my usual use case is 35-50 tabs open in chrome, so sometimes I don’t even have
the icons showing), I can see the (#) in the tab title, but this request is to update the icon like gmail does for unread emails (it’s buried in the gmail options somewhere):

I’ve seen other websites that do this too for things where count matters, but I can’t think of them right now. Twitter maybe?
An icon change to show there was an update without a count would be good enough since I don’t really care how many updates the page has gotten, just that it has been updated or not since I last read it.
