@ rantom: if you copy the transitions.ini from black plastic to your "main" hildon-folder, you'll get those snappier settings to all of your themes. Run this in terminal (rootsh must be installed):
sudo gainroot
cp -rf /usr/share/themes/blackplastictheme-themedir/transitions.tmp /usr/share/hildon-desktop/transitions.ini

And then reboot.[/QUOTE]

but how about if we want to return back the default transitions to each themes. thanks in advance.
