I just upgraded to Eclipse Indigo SR2 and am dismayed to find that whitespace character opacity can no longer be adjusted by clicking on the words "Whitespace characters" within the Preferences -> General -> Editors -> Text Editors pane.
Was this feature removed? Or was it always part of Zend's Eclipse + PDT distribution? (I was using Zend's distribution, but replaced it with eclipse.org's, because Zend's is out-of-date.)
