Safari 3: No More Blinky
I have yet to see this mentioned around the Mac web, but along with session saving, draggable tabs, very sexy inline find, resizable text fields, some enhanced privacy options and bookmark/history searching, the Safari 3 beta for OS X (and likely Windows as well) presents a long overdo fix for a very annoying rendering bug:
In Safari 3, DHTML content displayed over Flash content no longer disappears or displays erratically!

Thanks, Apple. Now fix that memory usage, and get me Flash on the iPhone. Pretty please?
(Note: I was wrong. Flash on the iPhone is unnecessary. Please direct resources accordingly.)
