I left Ubuntu for Xubuntu because there no longer are any tabs for navigation between documents/applications. Using some keyboard combination to jump between documents/applications simply is a big step backwards in my opinion as overview now is completely missing and navigation now is less straight forward.
I did however recently come across someone who claimed that tabs might be achieved through Compiz somehow. It was never explained how, so I'm a bit lost at the moment. How can I do that? I can't find anything in CompizConfig Settings Manager... I would love to be able to implement tabs in Ubuntu. How can I achieve this?
