Sorry, I don't want to spam you but I thought about a possible  
solution for that issue.

The first thing one could do is to subclass LazyListMorph to have a  
Morph which permits the displayStrings to keep their color. Then  
there is the need for a new PluggableListMorph which overrides  
PluggableListMorph >>listMorphClass to get this subclass of  
LazyListMorph. The next thing is to construct another OBMorphBuilder  
which changes #listMorphForColumn:.

Then a new builder exists which delivers browsers with the wanted  
property. I don't know if there are other classes which have to be  
changed (OBPane?) or if there is an easier solution. Please give me  
your opinion.
