Fixing numerous bugs in SectionScroller - the fast scroll thing on e.g. contacts - (so it doesn't get stuck on screen, so it follows your finger, and some nicer animation on it) Making Helium (the web browser) smaller in terms of size by removing some unused junk, and making it start up faster (from around 6 seconds down to around 2.8s for me) Testing an X server upgrade which removes numerous flicker/visual glitch bugs
