I've redone the thumbnail manager for Pixie and it's quite fast :) Besides 
loading the thumbnails as they are viewed instead of all at once, I've 
noticed QIconView is much faster inserting items when hidden than when 
visible. For 1500 items, inserting takes ~40 secs while shown and ~6 secs 
while hidden. This includes when disabling Pixie's "view the last item 
inserted" behavior.

It appears QIconView repaints or does layout calculation whenever inserting 
items even if they are not visible. Is there an easy way to fix this? I don't 
mind requiring users to wait until all items are inserted if it's going to be 
so much faster when entering a directory...
