Hello, hello.
I felt compelled to register for MacRumors to respond to this thread.
I think the notion that the new Safari omnibar is dumbed down for "stupid people" aka "moron" who comprise the "lowest common denominator" of computer users is a little over the top.
While I do agree that Apple could appease even more people by allowing both, I think most users will see this as a step forward, not back. After having an affair with Google Chrome, returning to Safari was frustrating until I found Safari OmniBar.
It's not that I, "don't know the difference between a search and a URL," it's that sometimes I want to search, sometimes I want to go to a URL. I believe modern computing is so advanced that my browser can correctly infer what I meant.
In fact, for those of you who were used to a URL bar that automatically adds ".com," you were relying on the built-in thinking ability of your browser, too. They changed the mechanics of it, but implying that it is a modification to help morons is just as silly as calling you a moron for relying on your browser to add .com or .net for you.
@dpk: not a perfect solution to your problem, but try using SnapBack (cmd-opt-S) to get back to your most recent search.
Lastly, I've found solutions for many issues over the years on this forum, and I've considered joining in the past, if only to thank the many contributors. Thank you to all of you.
After I read this thread, I knew at once that I must finally join you to bless you all with my wisdom, and offer my thanks. Thanks for having me!
