Question regarding differences in UI between Beta2 and latest q-build

Hello,

I apologize if this was announced somewhere. I am wondering if I am
doing something wrong or has the UI really changed between Beta2 and
latest q-build (20051218)? Just two quick examples, the Output window
doesn't use entire screen width anymore (combination of Projects and
Navigator windows now use entire screen height) and Runtime window
can't be tabbed together with Projects and Files windows anymore. The
reason why I leave the possibilty of me doing something wrong is
because I had to spend something like 5 minutes to customize the
(otherwise completely blank - is it supposed to be like that after
fresh installation?) workspace.

On the usability side of the new UI organisation (if it really is new
organisation), all I can say for now is that it is... unusual. It'll
take me some time to get used to it. I really liked "tabbable" Runtime
window and my wide Output window :).

Thanks for any insight.
