The font size when viewing an issue is quite large (12 - 13pt, I'm guessing). It would be nice if users could shrink the font size based on their preferences. Some tickets have a lot of custom fields and long descriptions, causing the page to be very long. It would be nice if the font wasn't so big. But at the same time, I'm sure we have some users who wish the font was larger, so it would be nice if the users could tune this themselves.
