This script will update the ZenDesk tab titlebar to be similar to the following:
At a glance, this shows the ticket status (N for New, O for Open, S for Solved, H for On-Hold), the ticket number and the ticket title. This is instead of the default title that ZenDesk shows... which is the same thing no matter what page or ticket you're viewing.
I use the Tampermonkey addon (Firefox, Chrome, Edge) within my browser. I've added the script within this repo and pasted it into the Create new script within Tampermonkey.
