Victor Cajiao posted a video on Twitter showing how Safari treats tabs in an Expose-type fashion if you have a Safari window open with a single tab.
After watching the video, I tested it myself and found that if you do this with a Safari window with multiple tabs, the Safari window itself doesn’t minimize. However, if you select one of your existing tabs and drop it outside a Safari window (i.e. the Desktop), it will create a new Safari window with the tab’s contents. Another cool feature right there.
But that’s not it… I also saw that Safari lets you move tabs between windows. If you select a tab just like Victor does in his video, and then drop it into a second Safari window, the tab moves right over.
All good stuff that I wasn’t aware of before.
