I downloaded Categories a few ago ago and now have everything in one page...
i'll look into Categories SB..
I'm just not a fan of the folders being a bit pixelated; im assuming it all looks well on an iPhone or iPod Touch but obviously they can look a bit grainy on the iPad.
SB just integrates Categories more seamlessly with the springboard. Well worth it, I think. You're right, the folders aren't quite right, being made for the phone.
As far as Locktopus I see no universal or automatic way to enable and disable lock, just doing it one app at a time.
