There's no category for the feedback tracker itself....so...
Currently you see user names in bold text while ticket description/headers are hard to read.
I think people are not interested in user names but in tickets.
Please remove the bold text from user names and make ticket headers/descriptions/links bold.
All in all I can see much too much user interaction here. I'm not interested who adds himself to a ticket or similar nonsense.
And why can't I choose a dark background? The white background with hard to read fonts is cancer for my old eyes!
