I've recently had to learn Jira, and holy cow the iconography (and really whole UI/UX) is awful. I have to expand the left panel and waste a crap ton of real estate on an already way overcrowded page to get textual labels instead of icons consisting of variously arranged boxes. Horizontal boxes = backlog. Vertical boxes = active sprints. Stacked shrinking boxes = releases. Of course, they're all single-color outlines with little visual distinction between them all. Who thought of this? What would have been so awful with just words or even abbreviations? Heck, why does this even need to be in an almost completely empty sidebar instead of using the dead space in the top navbar?
