Together with the Frame Viewer and Slots & Properties, the Knowledge Browser is the most significant component of the user interface for a Knowledge Engineer and offers all the necessary possibilities to search, view and modify knowledge (with the proper user rights).

Furthermore, the demo show that switching on the option "Connect Workbase to Knowledge Browser" under the Appearance tab of the Tools>Options window will enable you to see the (Taxonomy) relations in the Knowledge Browser related to the selection in the QTaxonomy node.
...
You can also remove frames. However, a knowledge base is always protected against this modification as this might have influence on the projects used with the knowledge base. "Under water" the frames are represented by numbers (pointers), when you delete a frame, these pointers are renumbered. And as a result projects with this old numbering will not work properly anymore (you will be warned). Therefore, when you want to remove a frame, you have to remove the delete protection (File>Allow deleting frames ).
Furthermore, you are able to group relevant parameters and relations in classes in the class tree. You can create a new class and arrange existing classes in the class tree on the left side of the Knowledge Browser and drag and drop parameters and relations in these classes.
The purpose of classes is to organise your parameters. You do this by selecting any existing class and press the right mouse button.
...
To reorder the classes you have to press the button between the forward and back buttons of the knowledge browser (field 2). This button will switch the class tree view between Class List, Domains and Class Tree view (the default view). Please note that button has the name of the view you will switch to (and not the present view). In the Class List mode you will see all classes presented in a syntax showing sub-classes after a dot. So, a sub-class of "Top Goals/Undefined" class is presented as "Top Goals/Undefined.sub-class". You can simply drag and drop the presented class entries in order to manipulate the order of classes and sub-classes. The only class you cannot move is "Top Goals/Undefined".
