I was able to restore the "Favorite People" tab in the default HTC Home plugin by disabling the ToucuFLO Cube, deleting HKLM\Software\OEM\MASD\QuickDial, and then adding "Tabsetting" = "1,2,4,3,6" to HKLM\Software\HTC\HTCHome, which specifies the order I want the tabs in (minus the Music tab, which I never use).
Works like a charm!
