We finally comitted the results of the first KDevelop Conference to the kde svn (branches/work/kdevelop4-merge). This is a port of the core modules to Qt 4 including some major cleanups. Highlights are the composite item model and the filter model. They allow us to manage all kinds of data (classes, files, etc) and to perform actions like filtering or sorting without much hassle. More changes to appear at the aKademy meeting this year.
