One thing that would be REALLY helpful to developers would be a place that documents the code/classes that make up the dolphin codebase. A lot of this can be auto generated by a package such as Doxygen.
A good example of one of these class references would be what MediaWiki has done with their code at: http://svn.wikimedia.org/doc/
They simply have an automated system that runs on their SVN and generates the Class documentation from the source code/comments. I know that this would have saved see more me HOURS of tracking down which classes/files contain which member functions that need to be called....
