If you really want a 'browse' mode, why not add the actor to Kepler's 
'official' list of supported and documented actors and just include it 
in the actor tree?
    It could be done under the menu item, but it would require the 
system to examine all java classes and determine whether they are 
entities or attributes (or we put all the entity/attribute classes in a 
single location).
