Using JIRA 6.1.
There's a default screen tab named "Field Tab". When it is only the single tab in a screen, the tab isn't visible at the View Issue page.
When I add the second tab, the View Issue page shows 2 tabs: Field Tab and the second one.
The question is: can I add a second tab and see only the second tab at View Issue page? All fields from the first tab should be shown as earlier.
