Not yet, but I'm pretty sure that SW has heard people's frustration. If you search you will find a number of threads expressing the same feelings as yours.
Like Jerry said Solidworks heard the frustration. Jerry and I were at a
round table discussion at Solidworks World and this was a topic that got brought up.
Someone from Solidworks asked the question on what interfaces do you
not like or find annoying. This was one of them. It also got brought up that
Solidworks was in the process of making the tab builder work both ways.
Hitting the "Apply" button as well as off of the tab. Obviously not there yet.
I personally am still with 2010 and this is one enhacement (which was asked for by users
according to Solidworks) that doesn't make sense to me. I like it just the way it
is in 2010.
Just to add that it still behaves the same in SW2011 SP 3.0 EV i.e. you must hit "APPLY" for changes to stick.
