That's an impressive tweak, for sure! I have a similar one for WebOS. However, these springboard extensions seem like a step backwards from the [I believe] superior option that is FolderEnhancer.
I mean, there's really no need for more than two pages of icons anymore - not when you can nest them so efficiently.
I guess this could be cool if you always want your Search page to be no more than two swipes away in any direction... ?
Options are good but I have combined Waparound and Running List. That puts the active apps as a list on the spotlight page. No more double clicking and messing around. A flick of the screen and instantly i can see what I'm looking for and I assigned the double home to Remove Background. Very handy
