There had been a big quarrel when Jira was introduced.
Someone from Atlassian promised help, but little seems to have happened.
After I have been using Jira for a while, here is what get's on my nerves the most:
I always grind my teeth when I get to the page and Jira forces me to acknowledge its own stupidity by requiring me to click on the login link myself.
But maybe I am just spoilt by Idea's usability.
