I am talking about a Tree/Preferences type view of the XML file. Didn’t there use to be one in an older release?
Either the Grid tab or Outline view should give you this… if you mean something else, please explain.
The Source tab should be smart enough to look up class names when ctrl-space is used, it should support a ctrl-click to jump to the class, and it should validate class names where possible.
Already filed. We are very pro-autocomplete around here.
