I feel so thick now, I actually KNEW that as its one of the first things I did on my phone instinctively after using an iPod Touch which I believe does it exactly the same way.
I still wholeheartedly recommend a different launcher though, its true when people say the LG one is slow in comparison. I couldn't even tell much difference until I switched, now switching back trying to fix an issue I was having it seemed painfully slow in comparison to what I had been using.
