Hi Marcel,

Thanks for the change set.  Unfortunately when I try to file it in the method below gets a DNU
sending: self environment.  It seems Browser is missing the #environment method.

I'm using a Squeak 5.1 image.  I'm willing to upgrade it and played around trying to do that
but no luck.

What am I missing?

Lou

hierarchicalClassList
	"classNames are an arbitrary collection of classNames of the system.
	Reorder those class names so that they are sorted and indended by inheritance"
	
	| classes flatTree |
	
	self flag: #performance. "mt: Creating the hierarchy is *really slow* for the full class
list. Skip it for now."
	self selectedSystemCategory = SystemOrganizer allCategory
		ifTrue: [^ self defaultClassList].
		
	classes := self defaultClassList collect: [:sym | self environment classNamed: sym].
	flatTree := OrderedCollection new.
	
	self
		flattenHierarchyTree: (self createHierarchyTreeOf: classes)
		on: flatTree
		indent: ''.
	
	Browser showExtensionClasses ifTrue: [
		| extensionClasses extensionFlatTree |
		extensionClasses := self extensionClasses collect: [:ea | ea theNonMetaClass].
		extensionFlatTree := OrderedCollection new.
		self
			flattenHierarchyTree: (self createHierarchyTreeOf: extensionClasses)
			on: extensionFlatTree
			indent: ''.
		extensionFlatTree := extensionFlatTree collect: [:ea |
			ea asText
				addAttribute: (TextColor color: (self userInterfaceTheme extensionClassColor ifNil:
[Color gray: 0.75]));
				yourself].
		flatTree addAll: extensionFlatTree].
		
	^ flatTree

And looking at the core classes like Behavior, ClassDescription and CompiledMethod will provide you with tools you can use.
