Cruz, for instance, unpacks results from websites like Google and then fetches the links, renders the pages, and displays the results in a tab with the same basic CoverFlow that Apple uses in iTunes. The browser also tracks your Twitter account in a sidebar in much the same way that Flock does. There's no reason to have a separate window that gets lost in all of your other tabs and windows. That essential information drip of 140-character updates is always available.
Cruz will download all of the links from a Google search and display them in a Cover Flow window at the bottom.
Fake is an ideal tool for website programmers and managers. You can use AppleScripts to control the behavior of the browser -- perfect for testing. While Cruz and Fluid are free, Fake costs $29, but it's probably worth the price if you're worried about quality control.
Fake combines a Safari browser with an AppleScript scripting tool. It's easy to drag a series of browser actions together into workflows to automate testing or onerous tasks such as filling in Web forms.
Fluid builds "site-specific browsers," which are stand-alone browser applications that go to one site and one site only. They're like Safari but without most of the controls and buttons. Opera has a similar feature and calls them widgets. They're quite useful in computer labs and other public settings where people could use an open browser for reasons that aren't necessarily what the kiosk is supposed to be doing. Each time you run the program, it will suck down the Favicon from the URL bar and use it for the icon to the site-specific browser.
If you need a simple application that goes to one website, Fluid will produce it for you -- no extra buttons, just the website.
Specialty Web browsers: Browse in 3-D with SpaceTime In Hollywood, some movie directors create fancy new user interfaces for science fiction movies just so we know we're in the future. After a tough day at the office staring at an inbox that is just a long list, we get to go to the movies that show the future heroes pointing and gesturing as the information floats and bounces across the screen. I'm sure that the future heroes will get the same mixture of spam and depressing credit card bills, but somehow it just looks so much more fun when these messages fly across the screen.
