Ok, I think I understand.  Is this what you mean?  For instance, let's us=
e =

http://dynapi.sourceforge.net/releases/dynapix/examples/dynapi.gui.explor=
er.html
for reference.

I hit the page, and I see it takes a very long time to load, as it loads
everything.  On the other hand, when it runs, it runs very quick.

Say we load only the top level, then load only if required by expanding a=
 tab.
 The downside is that the application might seem slow.

So something aynchronous might be desireable.  Perhaps load the top level=
, and
display it, then continue to walk the tree breadth-first and load the dat=
a for
sub levels while waiting, and stop to handle any user actions?  That seem=
s
very complicated to me, but might be the right way to handle it for the u=
ser
experience.

Any comments or ideas how to implement?  It's a feature request, so I'll =
copy
the results of the discussion there and refer to this thread.
