Und bezüglich Tabs:
Keeping tabs on everything [arstechnica.com]:
"Most of the time, creating a new tab won't work exactly the same way it does in Safari or the Finder...
What you usually need to do is open multiple windows, go to Window on the menu bar, and hit Merge All Windows if the option is available. This will unify everything into multiple tabs on a single window, and will also often enable a new tab button as well."
