Tap SB is an upcoming Springboard modification powered by Cydia / ISpazio. It looks like “Spaces” on a Mac. The app would arrange 6 springboard pages in 1 in mini sizes. Allowing you to jump to any page directly.
To use the TABSB functionality you just need to double tap on the springboard and the 6 page view would show up, allowing you to select any one of those… (fig above)
Remember: This is an upcoming app
