To reduce the number of IGT related bundles and group those together that form a sensible unit the following might be a reasonable proposal:
MITK_BUILD_org.mitk.gui.qt.igtnavigationtoolmanager
MITK_BUILD_org.mitk.gui.qt.igttrackingtoolbox
MITK_BUILD_org.mitk.gui.qt.navigationdataplayer
This would form a core of IGT functionality for those who want to use MITK IGT.
further the functionality of the
MITK_BUILD_org.mitk.gui.qt.igttoolpairnavigation
might possibly be integrated as a more specific application.
