In the new JIRA there's no category for JIRA: there's no way of reporting
problems and suggestions for the JIRA system.
When creating a new issue in IDEA Feedback, the component list is missing
another entry: User Interface.
Most of the usability problems are in the user interface - wrong menu entries,
missing tooltips, non working keyboard accelerators, etc. This probably happens
also on the other JIRA categories, but I haven't looked there.
