I have been playing around with Jira for the past few days. I have created some issues and done some searches and created some saved filters.
Overall, I like Jira's interface. There are some rough spots like unnecessary fields on the create issue.
But by far the most confusing part is the three different buckets of issues: feedback, backlog, and development. Actually, if feedback, backlog, and development where three different views into the same bucket of issues, then I dont' think there would be any issues. That's how I thought it worked.
I had created several new isseus in feedback, if I then clicked Preset Filter->Reported by me, it would show all the issues I created.
I came back the next day and clicked Filter->Reported by me, and there was nothing. NOTHING!
That's when I realized the issues must be getting moved around from feedback to backlog to development? I now had to goto the development project and click Filter->Reported by me, to see my issues.
For me, that is the most annoying part (by far) of jira so far.
I don't see why JetBrains didn't use a single project and have 'feedback'/'backlog'/'development' be a custom field which default to 'feedback'.
