Yes, that are may changes.

I think I was a bit confused about
showHierarchy : show the real hierarchy of an class
and
showHierarchy : show the classes in  a package sorted hierarchically.

The first one is enabled by the hierarchy/flat-Button (show packages)
The second one is enabled by a "showhierarch" setting

You see I was unaware of the setting :) 
BTW, it doesn't change the way classes are displayed when I disable it.

Hi everyone,

I noticed that browsing Object take several seconds (5s on my machine). Evaluate Nautilus openOnClass: Object. 
After profiling, I found it's because of ClassWidget>>setCachedHierarchyClass: that calls SortHierarchically class>>buildHierarchyForClasses: with a big collection of classes.
But the browser opens on the package view by default, not the hierarchy view.
So if I replace:

ClassWidget>>showHierarchy: anObject
    showHierarchy := anObject.
    self selectedClass ifNotNil:[: class |
        self setCachedHierarchyClass: class]
by:

ClassWidget>>showHierarchy: aBoolean
    (showHierarchy := aBoolean)
        ifTrue: [ self selectedClass ifNotNil: [ :class | self setCachedHierarchyClass: class] ]

it solves the problem. 
But I don't know that part of the system well and I don't know if it's the correct thing to do or if we should try to improve performances of SortHierarchically instead.
So tell me what you think about it.

Thanks,
Camille
