OmniWeb 5 is looking much better.
It finally adopts the Internet Explorer history model, by which I mean that it has a persistent, global history that’s organized chronologically. You can view it in the browser window, like in Safari, or in a separate window—and it’s searchable. So OmniWeb has gone from the back of the pack to the front in this regard.
At last you can see the URL at the bottom of the window when you roll over a link.
It has the best implementation of tabs that I’ve seen. I may actually use them. The modifier keys aren’t as nice as in Safari, though.
It still supports the Shortcuts feature that I’m so fond of.
Downloading is still weird. You can’t download links by Option-clicking them, and the Downloads window won’t automatically hide files after they’ve been downloaded.
