I have a big gripe with Lion about the seeming disappearance of my three fingered left/right swipe for navigating my "history" in Finder. This was the same gesture used in pre-Lion Safari. Yes, the two fingered history swiping is nice, but it does not work in Finder. Anyone know how to get this back? It was available in the Dev. Previews, but not now. 
Also, two more gesture issues:
1) I can't use three fingers to swipe up and down my message list in Mail.app.
2) I can't use a two finger zoom gesture (pinch) to zoom in on my Mail messages.
