Hi,

I really like the way how OmniBrowser lists classes by hierarchy and  
with indentation. I just extended the normal browser to do the same.  
The feature is disabled by default and can be turned on with  
Preferences enable: #listClassesHierarchically.

If you like the change I would be happy if it would be included in the  
trunk. Right now it's here: http://source.squeak.org/inbox/Tools-rkrk.111.mcz
