hello all,
here is a change set with TwoWayScrollPane revisited for 3.7
and 3 new subclasses :
    TwoWayPluggableListMorph
    TwoWayHierarchicalListMorph
    TwoWayPluggableMultiColumnListMorph.
To build these, I've made a copy of the original classes (ie 
PluggableListMorph...)
and make them subclasses of TwoWayScrollPane.
after some tiny adaptations, it works well for me.
