This is a really neat idea, but it unfortunately doesn't seem to work. I put it in, and turned it to display in the Ticket View page. Problem is, it shows a white number 5 for all requester.
If you can fix it, let me know, I think this is pretty cool!
Works perfectly for my team - can't remember if I had to tweak the code or anything but it did show the white 5 on all tickets for a little bit. Maybe just refreshed the cache?
