Anyway yes, I can use JIRA. But it was a real shock to see the latest version of JIRA. It has a thousand papercuts, one of the worst is double clicking on text select stuff suddenly kicks fields into editor mode.
What I was remembering was JIRA Server 4.0, you can walk down memory lane here* - zoom in enough and you'll see each issue has a title, type, fix version, affects version, and so on, and then you end up going straight to the comments. Very straightforward.
