Cool :)

They recycle the views, showing only views for the items that fit on
screen and, maybe, a few extra at the edges. Using callbacks to get
the view and bind the data for each one.

There was a way to use Dolphin Smalltalk ListView to use its
underlying SysListView32 in virtual mode (I can't find it now).
There are HTML list widgets that also do that. Here is a case of how
to it with C# <http://www.codeproject.com/Articles/42229/Virtual-Mode-ListView>
Of course nothing of this helps you immediately, unless you're going
to implement such virtual/recycling lists in Morph.
