I just installed the "JIRA Admin Helper" plugin and it looks great.
But where I used it first it left me scratching my head.
I asked about a particular field I am not seeing and thought I should. Plugin said it should be there. Tried two fields, a "Parent Summary Field," and an "Extended Summary Field."
The plugin said:
<dl><dt>Status:</dt></dl>

<dl><dd>The 'Parent Summary.' field should be present on the form you are viewing</dd><dd></dd></dl>
