Thanks - I'll give that workaround a try. Can maybe use it to reconstruct a grid like the old one. I'm looking at reducing the number of home screens on the tablet anyway, but it's quite useful to have a different screen for each function (mail, video, radio/music, games etc).
Also I'm not sure we can really call the current method an overview any more, as using it takes more effort and taps than just doing it directly on the main screens. It's certainly nice looking, but as you say it's a real pain to use for the job it's supposed to do. The old one was much more functional, if not as pretty. Going back to it (or at least an option to switch between the two) would be very much a positive for me.
