there are a few missing features when it comes to tabs (IMHO).
* No "Close All" function (great for when you have finished one thing in a work space and are off to start something new)
* No Close button on tabs themselves (though this increases the chances of accidentally closing a tab)
* No docable window list
I personally would do away with using tabs if we had a docable window list feature
I believe though that the basics are there for good window management and in general it works well
Edit: I just right clicked on a tab and found two of the three options I wanted above...
