Jira drives me nuts with this. I have a 34" monitor and with six columns in our Kanban board I can see 4, maybe 5 tickets per column. With 10 people on a team it means constant scrolling to see what people are working on.

It finally pushed me over the edge to use user stylesheets. A bunch of "margin: 0 !important" and "display: none" and I get twice as much information on my screen at the cost of... looking polished I guess?
