Create a New Terminal Window from a Tab
In Mac OS X, 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 on some versions of OS X, you can drag your tabs all you want and they’ll slide around but won’t break away from the tab bar. But you can still make a new tab turn into a new window, here’s how.
The solution is easy, right-click on the Terminal tab and select “Move Tab to New Window”
This is necessary in Mac OS X 10.6 Snow Leopard, but I’m happy to say that this unusual behavior is fixed in Mac OS X 10.7 Lion onward, so in for those with the latest OS X versions, this won’t be necessary and you can drag and drop your Terminal tabs all you want.
Plus, Lion onward gets a full screen Terminal option, which is also a great feature for command line users.
If you have no plans to upgrade to Lion, you could also just grab iTerm2 and get these features and more.
