I’ve been using the Safari 3 beta since the day it launched at this years World Wide Developer Conference. Overall, I’ve had a very pleasant experience with the browser, it hasn’t crashed as frequently as you’d expect with beta software and feels very well polished for such a new product.
Two features have stood out for me which I’m using on a constant basis. Those are the rearrange tabs, and the new on page searching feature labeled as “Inline Find.”

Both of these features are amazing, both in looks and function, I assume I’m dragging tags dozens of times a day, and I using the search feature at least five times a day on average. No more is searching on long pages clunky and time consuming, I can simply hit Apple + F and start typing, with results highlighted in orange instantaneously.

What features are you liking in the Safari 3 beta? Are you using it as your browser full time, or are you still on the previous version for extra stability?
