Version: svn trunk (using KDE 4.3.0) Installed from: Ubuntu Packages Doxygen has the @category and @package comments which would be very useful to use in the class browser. For example PHP (and probably many other languages) you often use frameworks with often very good inline documentation (esp. the two comments above are used). Now consider you have a local project which leverages a framework with like hundreds of classes and functions. Your project often has far less classes. Right now all are grouped in one view. It would be much better to have them grouped by @package / @category, which would essentially separate your local classes from the framework classes.
I'm not sure this belongs into the classbrowser. Parsing doxygen comments should be part of a doxygen plugin and that one then would need to expose some API to other plugins.
