Think I know what you mean - I'll be interested to see it in action.

There may be a bit of a problem there - the way the tree list is
implemented each node in the UI holds the index of its associated item in
the item array. This was the original implementation and it worked fine
for me so I didn't change it. This is good as long as nodes are
continuously added to the tree but if you remove nodes (as in toggle favs
off) the index of the following nodes will be off.

I couldn't see an easy way of doing this, so once a node in the favourites
tree has been loaded it remains there even if the favourites are updated.
This is my first attempt with the QT / Myth library though, so there may
be something easy I'm missing.

I moved some stuff from the main game tree to the tree item class as well.
This should clean up the game tree code somewhat. Hopefully, all you
should have to do is implement a different algorithm for selecting the
child nodes in fillNode - most of the rest sould fall into place from
there.
