I'm not sure how I feel about those... I think they'd definately cause a lot of clutter. Given the scale of the 770 it's not like you'd have 40+ apps installed at a given time. (And if you did, you're probably nuts enough to know where each one of them is in the menu tree) What might be cool is a customizable quick launcher (for example, I don't use the e-mail client... but it's always sitting there staring at me)
