FullScreen for Safari (I have it to double tap to get in/out of full screen mode)
GridTab for safari (nice expose like tabs in safari)
HomeButton in Safari (adds a home button in your menu)
Pull to Refresh Safari (acts as a Refresh/Stop button when you pull down)

Also u can try UserAgentFaker... with its toggle in sbs, it's quite handy.

These are nice tweaks that overall improves browsing with safari, many should have been stock... but well. 😀
