HelixLauncher - (for devices running 2.1) Very nice launcher app developed over at XDA Developers. Much like Home++ but very fast and stable. Features include:
-3 to 7 screens (swipe scrolling between pages)
-launcher bar at bottom for 4 user defined apps links (just drag and drop)
-double tap for screens preview
This has a thread up in the "Hack" section.
