Okay, maybe that's a bit of hyperbole up in the title above, but we're super excited about this system extension, Safari Omnibar
(we know, we know, totally late to the party). We just updated OS X Lion to 10.7.2, and alongside it, Safari 5.1.1. Although we've always liked Safari's rendering speed and integration with the OS, but preferred Chrome's unified search bar. Now we don't have to compromise...Now we can have the best of both worlds, as Safari Omnibar immediately makes Safari 100% a better browser for the following reasons:
1) it's transforms Safari's location bar into a unified search bar like Chrome
2) it's absolutely free
3) it's easily removable
There are few issues using Safari Omnibar
(notably not being recognized by OS X Lion's "reopen windows" feature), since it's not an endorsed extension, but rather an open source "code injection", which is explained as a more involved application plugins to modify Safari's behavior in manners Apple didn't intend their browser to do (and for shame). So far, no issues...worth a try if you've always wanted to slide on back over to the Safari camp, but couldn't quit due to the universal search bar feature.
