Chris Muller uploaded a new version of Tools to project The Trunk:
http://source.squeak.org/trunk/Tools-cmm.601.mcz

==================== Summary ====================

Name: Tools-cmm.601
Author: cmm
Time: 21 April 2015, 9:32:35.388 pm
UUID: 9a860ff9-21b9-48b6-9613-8a5f0303877b
Ancestors: Tools-cmm.600

- Added "Show System-Category in Hierarchy Browsers" so that HierarchyBrowsers may prefer to show their systemCategory or not.
- Let the new layout frame for FileContentsBrowser play nicely with the horizontal smart-splitter algorithm; by not making a one-line list.

  I provide facilities to explore classes in the context of their subclass hierarchy.
  
  My classDisplayList instvar uses indentation to show the subclassing relationship between the displayed classes.
