FEAT: Show expired token account as non-connected instead of ignoring them

[4javier]

In my work email I get a 1-week expiration token.
After that time I stop getting notification from that account and it doesn't get listed among "connected" ones, until resigning-in, but I could overlook that.
It would be nice to have a badge showing there are accounts not connected (the cookie should still be there after all), and maybe a quick link on right click to google account page where signing in again.

This is a good idea. However, I'm unaware of a method to detect a logged-out account using cookies. If you're familiar with a technique to identify the presence of a logged-out account, we could modify the icon's color accordingly.

I tried to give a look at the various cookies set by gmail responses, but unfortunately it looks way more complex than I expected.
I suspect token could get "split" in various requests for security purposes.
Even asked on Gmail community forum, but no help.
