Create a New Terminal Window from a Tab
In Mac OS X 10.6, the Terminal app reacts differently than Safari and other apps that use tabs. When you want to drag a tab into a new window in Safari or Firefox, you just drag it outside of the tab bar and it becomes a new window, it’s simple and intuitive. I agree, but Terminal app doesn’t behave like this, you can drag your tabs all you want and they’ll slide around but won’t break away from the tab bar.
The solution is easy, right-click on the Terminal tab and select “Move Tab to New Window”
I’m happy to say that this unusual behavior is fixed in Mac OS X 10.7 Lion, so in another month or two, this won’t be necessary and you can drag and drop your Terminal tabs all you want. Plus, Lion gets a full screen Terminal option, which is also a great feature.
If you have no plans to upgrade to Lion, you could also just grab iTerm2 and get these features and more.
